Z-fighting between flat texture and stencil at long distances was occurring, showing up as a "shimmer" at a long distance from the camera. Just increasing the vertical shift of flat texture.
Addressing this bug: https://github.com/ZDoom/gzdoom/issues/3246
Mark Actors meant to travel early so their flag can be written into the snapshot, followed by moving them over all at once at the same time as previously. On finish, destroy any marked Actors to prevent duplication in hubs. Switch to a unique function that does the verification instead of ChangeStatNum and lock out STAT_TRAVELLING entirely since it shouldn't be used for regular gameplay.
Added safety barriers for STAT_STATIC and STAT_TRAVELLING to avoid potential exploits. Properly clear all internal fields pointing towards non-read barriered data and always relink properly when finishing travelling. Moved ZScript callback to after travelling has finished for all Thinkers, that way everything is initialized correctly. Allow arbitrary thinkers (excluding native ones) to be added to the travelling list (for Actors, their positioning will need to be handled by modders). Ensure lights get re-enabled after travelling.
Added a warning if a networked Object or non-client-side Thinker was erroneously destroyed manually while predicting. This only applies to ZScript since this is the only place it's relevant. Added a warning if a non-client-side Thinker was spawned while predicting. Sweep objects before backing up while predicting to ensure invalid pointers aren't captured.
- add submodule update scripts
- remove auto-setup scripts, they don't work anymore
- copy zmusic.dll into build folder (this may need to be also done on Linux sometime)

- fix for case sensitive systems
Allows the SavegameManager to destroy all saves related to the current UUID session so hardcore mods can enforce this safely instead of needing to go nuclear.
Allows specify optional files from the commandline (note: this currently isn't hooked up to the filesystem proper for marking, this is purely for the file parsing until then).
