added fix so Pong works on whatever subtly different versions of pygame/sge Fedora sees fit to install
More work
* Semi-functional realtime raster plot visualiser
* More wiring - reward and punishment signals wired to poisson noise
* Fixed really stupid bug with rates being sent rather than ISIs!
SpiNNaker pong before refactor
Refactored into modules
Fixed a load of small bugs and implemented even crapper hard-coded network
Further simplification of stuff - Still not doing a lot!
