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.
These shouldn't be left as they'll now point towards potentially invalid memory and also cause errors with serializing. Arrays and maps holding them are cleared. Also unlinks and relinks inventory items correctly from the hashmap on traveling.
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.
