Title: Rake tasks to prepare project for release

Looks like v0.2.0 was released without the libusdt files, so it's not possible to install the gem from rubygems (errors out trying to find usdt.h).

This is a guess at a solution, to have rake run a few commands to checkout the submodules and clean them before pushing files to rubygems.
