Physics Collider + Gamelog again

Slightly frustrated at the loss of a good streak of github commits.
While I realise the last couple were extremely small they were, at the
very least, commits.

This change brings the beginnings of the Physics collision detection
that works at the moment. In addition, there were some things I
overlooked with the gamelog again that meant certain things weren't ever
going to get expanding upon. Sadness, really.
