Cleanup: avoid spurious updateDiveInfo() calls

Browse source 
In 2e230da361 the dive-selection signals
were unified. Sadly, this was done in a suboptimal way resulting in
numerous calls to updateDiveInfo(), which refreshes the main-tab.

Firstly, the MainWindow connected to selection changes from both,
the undo-command and the divelist. Secondly, every selected dive
in the divelist caused a single signal.

Thus, connect only to the divelist (this is necessary for user-initiated
selection changes) and only send a single signal in the divelist
per selection-reset.

This is still less than perfect as updateDiveInfo() is called even
if the current dive doesn't change.
