setupify

* move library into mkt
* move data files into mkt-data, a nice easy path for setup.py to install
* make bin/mkt a symlink over so its backwards compatible

At the end of this you should be able to `python setup.py install`, then call `mkt` and have the same result as `mkt/bin`. This isn't enough yet though, next we need to add in the root command and make it templatable and fix up all the paths on the fly.
