Initial commit
Use tablocal variables

So you can open multiple time-lapse views on different files in the same
session.
Make buffer mappings local
Experimental blame feature
Blame works much better now

git blame can tell us the old line number with -n. Tempfiles are
probably neater than messing around with registers.
Blame from the current revision
Continue from the blame point after a blame
Do mappings in all buffers
Be better about files with 1 or no revs.
Use original line number for Blame

Rather than the one the git blame command printed out. It sometimes
prints out a filename instead in that column (probably if the blame
takes you back across a rename or something).
Merge remote-tracking branch 'upstream/master'
