Update git-lkgr with --create and --name options.

Update git-lkgr with --create and --name options.

The previous --force-branch option is renamed --checkout (the old name preserved for backwards compatibility).

Usage:
  --checkout         Create a branch and check it out.
  --create           Create a branch.
  -n, --name <name>  Specify the name of branch to create or reset.
                       This will force the branch using 'git branch -f '.
  -q, --quiet        Quiet.

... because we should show the prompt even if --create wasn't passed; otherwise
the script is quiet when LKGR can't be found.

Alternately, if --create isn't given, just show the 'There is not master
commit...' message and exit.

Please take another look.

Done by asking the user to use --checkout if they want to create a branch that
requires deps2git to be run and committed.

As discussed in person, I feel like this command (like pretty much all git
commands) is too overloaded and trying to do too many slightly different things.

Ideally we'd break this into a couple of porcelain-y commands for the individual
parts you need, and have the main script either go away or be a thin bit of
glue.

But you don't need to do that now.

lgtm.
