Title: Use the Mountain Lion version of MacVim for non-Mavericks machines.

The commit that started using the Mavericks version of MacVim made it so Mountain Lion no longer works due to a dynamic linker lookup failure. The new one is linked against a version of perl that isn't present on non-Mavericks machines. This is causing maximum-awesome to fail its setup on non-Mavericks machines.
