This introduces `git root` which outputs the root directory
(the directory that contains .git).
The same can be accomplished by `git rev-parse --show-toplevel`.
`git root` is much more intuitive and easy to remember.
All it does is set the arguments for rev-parse

Hi,
I don't know if I can just send a patch for a new "command" in git,
I probably shouldn't. Well, i thought it's anyway better explaining
this way than just asking for comments.
With the kind of projects i have been involved with in the recent past, I
have had to deal with subprojects inside projects and for many reasons had
to find ways to find the root git folder and at times to "cd" to it.
The obvious choice is to go for `git rev-parse --show-toplevel`. But, this
to me doesn't seem very _intuitive_ and `git root` does.
bzr has `bzr root`. hg has `hg root`. So, for programmers i am guessing
this pattern would also be _instinctive_, and i am thinking why not `git root`?
