[WIP] bin: custom git commands

[joyeecheung]

This implements a custom git command git node that automate the landing process.

1) To land single a commit:
   git node just <PRID>

2) To land multiple commits: 
   git node apply <PRID>
   git rebase -i upstream/master  # edit every commit that's gonna stay
   # on each stay
   git node ammend <PRID>
   git rebase --continue
   # when the rebase is done
   git node final

Still a WIP, trying to port everything into node scripts..

@joyeecheung just want to know am i mistaken or this should be git-node instead of git node
as we have git-node in package.json?

[joyeecheung]

The git custom commands work like this: if you have an executable named "git-*" on your path, the it will be run when you do "git *"

@joyeecheung this PR looks great! Great Work.

This looks way too cool.

Just setting my review to "comment" while you finish your wip.

Oh....I know why my pushed commits didn't show up here now, it's being merged from the branch here now that this repo has been transferred.....I'll close this and open another one from my fork.
