Title: Run git submodule update after initial clone

Some repositories require that submodules be initialized and updated to
be properly built. This is now done during the download phase for every
repository.

This was required for the latest version of the Calabash podspec, which now includes calabash-js as a submodule.

I'm putting this pull request out there looking for feedback. Not sure if we want to add another parameter to specify whether you want submodule support or not, but I figured this was the simplest thing I could put out there and get comments on.
