mass-rename: update source files (gyp lists, #includes) to reflect
a rename. Expects "git diff --cached -M" to list a bunch of renames.
To use:
1) git mv foo1 bar1; git mv foo2 bar2; etc.
2) *without committing*, ./tools/git/mass-rename.py
3) look at git diff (without --cached) to see what the damage is
