12ea31ef78 mapwidgethelper: use system_default_directory() for cache
The default location which is used when the
PluginParemeter "googlemaps.cachefolder" is not specified
should be ~/.cache/googlemaps on Linux or
/user/<name>/appdata/local/cache/googlemaps on Windows.

This patch moves the cache to the default system location
where we store the printing templates, cloudstorage and the
default user XML file.

1da4f91cc8 mapwidgethelper: use dynamic creation of the Plugin object
The googlemaps plugin is about to support tile language
via the PluginParameter 'googlemaps.maps.language'.
To be able to pass the subsurface UI language (obtained
from the uiLanguage() helper) the Plugin has to be created
dynamically, only *after* the MapWidgetHelper is created.

MapWidgetHelper::pluginObject() now provides a QString which
contains the Plugin object and also include the uiLanguage
ISO value.

This string is used in mapwidget.qml as:
map.plugin = Qt.createQmlObject(pluginObject, rootItem)

This creates the Plugin object dynamically with the proper
UI language string, but also requires a couple of small changes:
- move the declaration of map.mapType after the
Qt.createQmlObject() call
- assign map.activeMapType after map.mapType has a value

98e869d4f1 mapwidgethelper: fix wrong logic in selectVisibleLocations()
Looking for already existing locations with
m_mapLocationModel->getMapLocationForUuid() will not cover dive
sites which are too close to each other and are skipped when
creating MapLocations. See reloadMapLocations() and the usage of
MIN_DISTANCE_BETWEEN_DIVE_SITES_M.

Constructing a new QGeoCoordinate for the already retrieved
dive site (ds) coordinates ensures that we are traversing
*all* dive sites at the backend and not only those visible on the map.

Fixes the issue where not all dives in the DiveList are selected,
even if a dive clearly happened on a location currently visible in
the map viewport (map -> context menu -> select visible dive
locations).

93896e54db mapwidgethelper: add the selectVisibleLocations() method
The new method selectVisibleLocations() contains a routine
to find all visible MapLocation objects in the Map viewport and
select the dives associated to said MapLocation objects.

This method is to be invoked from the QML context menu.

d421660f91 mapwidgethelper: support tracking of all selected dive sites
MapWidgetHelper::centerOnDiveSite() now checks if more than
one dive sites are selected and finds the most top-left and
bottom-right ones in the coordinate system to form
a rectangle.

It also supports the special cases where a selected dive site
does not have coordinates or the case where only a single dive site
with GPS coordinates are selected.

TODO: implement mapwidget.qml::centerOnRectangle()
This QML function will receive a QGeoCoordinate based rectangle which
has to be centered in the viewport with animation.

4d698310ff mapwidgethelper: add methods for editing MapLocations
updateCurrentDiveSiteCoordinates() should be called from
QML when a marker changed it's location. it emits the coordinatesChanged()
signal, which should be tracked in the MapWidget class. The MapWidget
class should emit the same signal to the MainWindow (Marble does that).

editMode is now a boolean property, which should put the QML map into
editing mode.

5e57e42874 mapwidgethelper: add the same logic for markers as in globe.cpp
The marble globe tracks dive sites with the same name and discards
such that are less than 50 meters apart.

We already store names in MapLocation objects, but using a
QMap<QString, MapLocation *> to check the names is probably faster
with the expense of using more memory.

c078e350e0 mapwidgethelper: emit a selectedDivesChanged() signal
The signal emits a QList<int> filled with dive idexes from the
main backend dive table.

The MapWidgetHelper QML instance handles that in onSelectedDivesChanged().
This will only be needed for the mobile version, as the desktop version
should connect it's own slot in MapWidget.cpp.

91302b3d8b mapwidgethelper: add means to obtain a small circle radius
Based on a QGeoCoordinate, calculateSmallCircleRadius() calls
some QML Map methods to obtain how big a circle is in meters if
a circle is drawn over the Map widget with radius SMALL_CIRCLE_RADIUS_PX
pixels.

This is called a "small circle" of a sphere:
https://en.wikipedia.org/wiki/Circle_of_a_sphere

This "small circle" radius becomes huge if the map is zoomed out, while
quite small if the map is really zoomed in.

The idea behind this circle is to be able to select multiple nearby dives,
when clicking on the map (TODO).

The function in QML centerOnCoordinate() is now renamed
centerOnMapLocation() and accepts a MapLocation object, so that
a marker is selected (based on UUID).

In MapWidgetHelper::centerOnDiveSite(), the pointer to a MapLocation
is retrieved via MapLocationModel::getMapLocationForUuid(). Added in the
previous commit.

a50e9866d5 qmlmapwidgethelper: maintain an instance of MapLocationModel
The idea here is that the QML code should be able to fetch a model
from the MapWidgetHelper instance which is instantiated inside the
QML code; fetch it in the lines of "mapHelper.model".

This way, updates at the backend would be reflected on the Map QML widget.

f5882362d3 mobile-widgets: add the helper class MapWidgetHelper
The idea with this class is that it should be used by both the mobile
and desktop version.

TODO STEPS:
1) the class should be registered in both the mobile and desktop version
with qmlRegisterType<MapWidgetHelper>...
2) the MapWidget.qml should create an instance of this class.
3) this way the helper will be part of the QML and both the desktop and
mobile version can have access to it.
4) the desktop version as a first implementation can just use findChild()
in desktop-widgets/mapwidget.cpp.
5) desktop-widgets/mapwidget.cpp on the desktop should just translate
calls from the rest of the desktop-widgets to this helper class.
6) the mobile version access to this object would be easy but is off the
scope for now.
7) the idea, when implementing the desktop support is to make it so
that when implementing the mobile version later, no or only minimal
changes would be required to the MapWidgetHelper class.
