Dive site: Add button to display all dive sites

On the main dive tab, add a button that opens the dive-site selection
widget showing all dive sites. This is done by setting the "temporary
dive site name" to the empty string. Thus no dive sites are filtered
and the "add new dive site" entries are not shown. Moreover, the
text is selected. The user can therefore immediately start typing to
activate the filter or enter the name of a new dive site.

The idea is that after downloading dives with GPS information the
user can select one of the close dive sites.
