Adds support for client-side Thinkers, Actors, and ACS scripts (ACS uses the existing CLIENTSIDE keyword). These will tick regardless of the network state allowing for localized client handling and are put in their own separate lists so they can't be accidentally accessed by server code. They currently aren't serialized since this would have no meaning for other clients in the game that would get saved. Other logic like the menu, console, HUD, and particles have also been moved to client-side ticking to prevent them from becoming locked up by poor network conditions. Additionally, screenshotting and the automap are now handled immediately instead of having to wait for any game tick to run first, making them free of net lag.
Fixed an off-by-one error on client IDs (these need to start at 1 as 0 is an invalid network ID). Morphing will now swap the client body's ID so it remains in the first 1 - MAXPLAYERS slots.
This is a combination of 2 commits.
Revert "New API for assigning unique network ids to objects"
This reverts commit e37c19b5b4.
This is the commit message #2:
Revert "Fix for Morph virtual"
This reverts commit 0ef042562e.
* deleting some unused code
* turned several class methods into static local functions in cases where they never were used outside this file.
* inlined the dangerous assignment operator in the only place where it was used.
Since most CheckGC calls are within the main game ticker, the engine can accumulate a lot of data when creating/deleting objects in the menu or other UI parts and never manage to collect everything
