Massive update to gitconfig, add VISUAL to zshrc

Most of the gitconfig stuff is stolen from other dotfile repos out
there, wherein I perused their gitconfigs, saw things that looked like
good ideas, researched what they actually did, then added them.

Of particular importance is the removal of my gitconfig [user] block
which has been moved to an included local file. This is to get around
the fact that I use this repo for work and personal stuff and don't want
a default with my legal name or online identity in it.
