Title: Replaced static libraries with git submodules

Instead of including the whole contents of pip and setuptools staticly, you can link to them. http://git-scm.com/book/en/Git-Tools-Submodules#Cloning-a-Project-with-Submodules

Changing the submodule to refer to a different version is easy too: http://stackoverflow.com/questions/1777854/git-submodules-specify-a-branch-tag (both pip and setuptools have tags referring to particular versions)
