Progression

This update adds some glitchy distortion effects and a new algorithm for creating endless content.

With undo available this means that I can generate enemies with hooks attached to them - which are extremely dangerous to deal with. I'm also presenting a selection of elements and adding a new one whilst taking an old one away. This means that each level of room has something the previous didn't.

I'm still experimenting with the look of things - I'm not entirely pleased with the hooks as they tend to obscure what's below them. I'd also like to make it clearer who's bad and good but I'm not decided on a decent palette yet.
