Show diffs before merging

Browse source 
This is what 5775e3..43d2a6 has been leading up to. Git fetch will be
called on all pkgbuilds, then the user is offered a chance to view the
diffs. If they choose to continue, merging happens. This allows users to
abort the install after viewing diffs and still be able to see thoes
diffs again if they try to install later on.

This also makes the git stuff a little more modular which should help in
organzing diff showing + pkgbuild editing.
