Berthold Stoeger f39596df06 Map: remove access to displayed_dive_site in GPS-filter model
The location information shows a list of dive sites at the
same location as the edited dive site. This was done by passing
a function to an "SsrfSortFilterProxyModel". Unfortunately,
the latter does only support function pointers without state
and therefore had to access the global "displayed_dive_site"
object.

Replace the SsrfSortFilterProxyModel by a proper subclass of
QSortFilterProxyModel that contains information on the position
and id of the currently edited dive site.

Update the filter model if the location of the dive site changes.
This introduces a behavioral change: editing the GPS location
will lead to an updated list.
