ability to manage bundles with submodules instead of tars

[phinze]

it's a common pattern to have one's vim dotfiles checked into git, and use submodules to track pathogen-style vim bundles

would be cool if this tool also helped with that sort of setup as well, though i realize it's quite different from what it currently does now.
