[WIP] Fix/Document compatibility with 0th/4th day glitches

[garrettjoecox]

My main goal here is to get the 0th/4th day glitches working, and if they are incompatible with any enhancements document it as such. For example, the Storing song of time glitch is incompatible with Faster song playback enhancement, since you are intended to void out during the playback which is now skipped.

Summary of changes so far:

• Remove enhancement toggle for save delay. Save delay will always be disabled unless we determine the player is trying to pull off the 0th day glitch
• Fix a few places where we were setting isOwlSave to false blindly which breaks 0th day
• Fix UB inconsistency with hardware, ensuring saving at the the Unused Owl Statue (in west clock town) will load you into the Mayor's Residence.
• Fix UB inconsistency with hardware for SceneTitleCard on 0th/4th days, and add our own messages for them (so it will render "Dawn of the Zeroth Day"

Alright I'd like some playtesting on this prior to merging, but I think it's in a good state.

Mostly just want heavy testing of existing save functionality to make sure I didn't break anything (Remember save location, auto save, pause saving)

Also feel free to try 0th day stuff. You can easily void out while playing SoT by typing void into developer console while it's playing back.
