I would've liked to make it use a single allocate function to do this very cleanly, but these cases were very clearly not meant to be standardized and use wildly different methods to allocate & free...
This caused some scary issues with P_SaveNetGame the other day, and it's making ACS net sync harder. Let's just cut this off right now.
Also fixed some scary mix-ups in some of the Lua archiving code.
An effectively useless global scope boolean that literally checks for the presence of a finish line, created in and used only by things we inherited from vanilla SRB2
* Battle-like item box respawn handling inverse of GTR_CIRCUIT
* Make battle fullscreen overlay forbid GTR_CIRCUIT
* Make GTR_ITEMARROWS actually do something
* Make everything related to points actually use GTR_POINTLIMIT
* Fobid sphere addition without GTR_SPHERES, to mirror ring addition forbidding
- The "never force a retry" condition is now `!G_GametypeUsesLives()`
- In GT_SPECIAL *and* GT_VERSUS, check for K_IsPlayerLosing before retry, instead of bespoke check
- Lines can be set to activate when crossing or bumping into them, with distinctions for players, enemies, and missiles+items.
- A new flag has been added to determine if a line special can activate more than once.
- Finish Line + Respawn Line are now handled like other specials. This means that:
- They follow the new line activation rules (so you can potentially have a finish line that you have to bump instead of cross)
- More importantly, they can be called as functions in ACS. (Player_FinishLine and Player_Respawn)
- Fixed linedef flags not being saved in save games.
