Windows installer: move the 32/64 bit check earlier

It makes more sense to do this on init and not have the user go through
any other screens in case this is the wrong binary.

After editing tags, get the right tags into the displayed dive

We forgot to clear out the pre-existing tags. We did this for the actual
selected dives that were being edited, but not for the displayed_dive, so
deleted tags showed up again on screen (even though they were correctly
deleted from the selected dives in the dive list).

Fixes #732
