Move DiveList related methods/classes to own file.

The DiveList classes were a partial mess (and some of it is still in a
messy state). The classes that deal with it where done in 'qtHelpers.h',
the extern global variable in dive.h, a few methods here and there. This
concentrates most - but not all - functions in their own file. The reason
for that is to make the new developer faster when looking for things: if
it's a divecomputer related method, it should be in a single file, not
scattered around.
