Modules installer

This is a simple modules installer (can't handle multiple files, or requirements yet)

It connects to http://jaspermoduleshub.herokuapp.com/

I added a `walk_packages` on `brain.py` so that modules can be installed in subfolders.
Spacing seems off on these few lines. The closing bracket (`}`) should be aligned with `self.PROCESS_FILE` and the contents of the dictionary should be 4-spaces inward from `self.PROCESS_FILE`.
