crbuild: A script to make building/running chrome/tests easier.
vmod: Added option to get open all modified files in a branch.
git-rebaseall: Renamed from rebaseall.

Should really be a sub command of Git.
crbuild: Items no longer use -i

Items are now "targets" and can be passed w/o the '-i'. They are first
considered to be items from collections.json, but if there is no match
then they are assumed to be a normal build target.
crbuild: Added support for Valgrind
crbuild: Printing out compiler/goma use when verbose.
Removed Git aliases. These are now in .gitconfig
