Bunch of crash fixes

Since the delay was announced, i thought i'd go ahead and port some of our major crash fixes from our dev build so the game is a bit more stable for those buying the game from the summer sale:

• Fixed lingering regret crashing on some kinds of bullets

• Fixed a crash showing up in st_hurt

• Fixed multiple misc issues and errors to do with our compiler

  • I dont really know the full scope of these, but issues this fixes include the cursor going faster than intended in all menus, and a couple of "index out of bounds request" crashes

• Fixed an engine error to do with arrays

  • This fixes a whole class of crashes that show up as "array_get" index out of range.

• the dumbass achievement now works on stage 1

• all bullet clearing code should be much faster

As a reminder, if you get any crashes or bugs, please send us the deets on discord or in twitter dms. there's a chance any bugs you run into aren't fixed in our dev build, and we wanna get this thing crash free !!!! Thank you all for playing!
