git-gui: Refactor 'exec git subcmd' idiom.
As we frequently need to execute a Git subcommand and obtain
its returned output we are making heavy use of [exec git foo]
to run foo. As I'm concerned about possibly needing to carry
environment data through a shell on Cygwin for at least some
subcommands, I'm migrating all current calls to a new git
proc. This actually makes the code look cleaner too, as
we aren't saying 'exec git' everywhere.
