When in dive site tab and some dive sites are selected, show only
dives at those sites. Simply read the selection and pass it to the
filter.
Start and stop filtering when switching to and from the tab,
respectively.

Add a "purge unused dive sites" button to the dive site list.
Connect it to a new PurgeUnusedDiveSites command. Implementation
was trivial: simply copy the DeleteDiveSites command.

If the name of a dive site is edited, it might wander somewhere
else in the table and thus out of view. Hook into the "dive site
changed" signal and scroll there.
The code is rather subtle as it depends on signals being called
in a certain order: First the item is moved in the model, only
then can we scroll to the correct place.

When adding a dive site, enter the name field of the new dive site.
Thus, when adding a new dive site, the user can immediately edit the
name.
The code is rather subtle: It hooks into the dive site added signal
before executing the command and unhooks afterwards. This only works,
because signals are executed in order of connect - thus the model
adds the index first and only *then* is the field edited.

Implement a dive site addition undo command and connect it to
the add dive site button. The added dive site has a default
name ("new dive site").

The LocationInformationModel used to sort its entries and was completely
rebuilt after every change. This makes it rather complex to support
incremental changes.
Instead, keep LocationInformationModel sorted by UUID so that indexes
are consistent with indices in the core dive site table.
Implement sorting by other columns than name and enable sorting in the
dive site view.
Finally, don't cache the list of dive site names for the mobile app,
since that would also need some rather convoluted methods of keeping
the list up to date. Calculate it on the fly.

Add a very simple tab-widget presenting the list of known dive sites.
The table is rendered using our custom "TableView".
The (mis)uses the "LocationInformationModel". It moves the items
to be displayed (delete, name, description, number of dives) to the
front and makes the others hidden.
Moreover, it was necessary to limit the geo-tag decoration role to
the name to avoid having the icon next to each column.
Make the trash-can icon active and the name and description editable.
This is modelled after the cylinders-table code.
