[PATCH] gitk: Add "First parent" checkbox
Sometimes it's desirable to see what changes were introduced by a merge commit, rather than how conflicts were resolved. This adds a checkbox which, when turned on, makes gitk show the equivalent of "git show --first-parent <commit>" for merge commits.

This is the same patch as the one I sent in
<http://comments.gmane.org/gmane.comp.version-control.git/160920>, with
the same issues discussed in that thread. I just brought it up to date
with current master.
