Fixed a bug where co-op players have no heads (sorry)

...

- Fixed a crash that can sometimes occur when continuing a run.

- Fixed Technology items crashing in AB+, I think

- Fixed Samael not having his pocket active as a co-op player.

- Fixed costume errors related to frequent cache updates.
- Reduced console spam related to costumes.

- Fixed some issues with technology lasers.
- Fixed an issue with melee damage calculation.
- Probably some other misc tweaks.

Tweaked around a handful of things in the code. As always please let me know if I broke something.

Fixed AB+ bugs introduced by the last patch.

- Modified how the scythe is moved and rendered. It should hopefully seem less jittery now. (This is the main reasn I pushed out this update.)

- Changed how Samael's blindfold/hood/hair are layered, and added a few new custom costumes. More will be added in the future.

As always, hopefully I didn't randomly break something while tweaking things in the code.

- Cleaned up a couple minor things with the Illusion Heart / Book of Illusions compatibility.
