Fix loading a second dive, after the first file was loaded.

This patch fixes loading a second dive-file after the first
one had been loaded. it simply clears some information and
makes sure that the current selected dive is invalid when
the file closes. I also did a bit of code cleanup on this one
to make things simpler in the future.
