CABot3 on Chip

We're going to start off just putting some of CABot3 onto PyNN.
That's the LIF stuff like control, vision, and planning.
We also need to get input from and output to the environment. We should be able to do that in Python, so we'll have some CABot3 agent running by July 1st 2014.
We then need to get the rest of it onto both chips.
As HICANN is a bit of an unknown, we've set a milestone of having it on SpiNNaker by January 1st 2015.
We've made HICANN CABot3 a non-specific milestone.
