* Haunted Heights! Smashing spikeball, Cacolantern, Spinbobert and Hangster, along with the Spider and Bat flickies and general decoration/ambience stuff.
* MF_PAIN and MF_MISSILE now support setting damagetype via their Mass parameter. The two existing conflicts - the fuse setting for the grenade weapon ring and the Cybrakdemon napalm bomb - had these moved to other free parameters.
* A_ConnectToGround is EXTREMELY useful for palmtrees and stuff.
* Some other, relatively hacky A_ functions.
* (Unrelated) Remove the need for a "Mario block mode" for the token by making it natively compatible.
* Spikes and their time-offsetting via that Lua script sphere made. Also allow for wallspikes to do it via their angle/360.
