Misc readme cleanup

The Git-based setup instructions previously pointed to
"TextMate/Bundles", but any modifications made in TextMate
were saved here. This made it slightly more difficult to
pull down new versions.

The updated instructions now point to
"TextMate/Pristine\ Copy/Bundles". Modifications made in
TextMate are instead saved separately as deltas in
"TextMate/Bundles", which means new versions of the
pristine copy can be pulled down readily.
