Added a python sample agent

- Learnt python (again).
- Asmodeus just makes random moves like "dummy", except written in python.
- Python programs need to be started with the -u switch to be unbuffered. Easier than expected.

TODO (still)
- Setup vm
	Involves kvm on motsugo? or qemu? kvm is faster, but otherwise are they the same thing? kvm's man page even calls it "qemu" (!?)
- Come up with long term scoring and agent handling protocol
	I have a few ideas about this. But I need the vm setup to test most of the stuff properly.
