v0.977

A new shot and a new terrain.

I was working through several ideas for new terrain that were very demanding, and then I thought of a very simple one: clouds that slow your fall, dispersing when used too long.

This led to an underwhelming shot called PUF. Clouds are nice, but PUF has strong competition. It joins the lowest tier of shots, giving you something fun to play with before getting a real weapon.

Bosses have had an overhaul: I have almost finished a new boss and finished setting up the dual boss fight for the final level. Bosses can now spawn one-of mobs, the walker boss for example will create one diver to support its walkers. And some changes to threat levels have been made, so the remainder of the dual boss fights harder, and bosses bypassed with GON are not impressed.

A couple of chunks are added, and some essential bug fixes have been applied.
