Update Notes for v0.97.3 (client-only update)

AI Editor is now available, allowing creating driving lines for the AI players (to add AI support to new levels and vehicles)
AI players can now be used in custom local games as long as the level-vehicle combination has AI lines (online support coming later)
Level Selector now has a filter to only show levels that have AI lines defined (for the currently selected vehicle(s))
Various small changes to the AI behavior
Quick game: All built-in vehicles are now supported, including Random and Choosable
Quick game: Player count can be adjusted, skill level can be mixed (e.g. half medium, half high)
Quick game: Lots of other new options: e.g. drafting, ghost races, missiles for AI drivers
Local Custom Game now always starts at the Session Init state where changing levels is still possible
Immediate Restart (Ctrl+Backspace by default) now starts quicker in time trials and special stages (if not random start time)
Moved HUD elements so that Weapons and Health are on the right and Time on the left side
Some GUI screens that require using mouse now show a message about that if opened with keyboard or gamepad
Automatically changing the camera target to the last AI player when finished and playing alone against AI
When changing the camera target for the first time after finished or wrecked, skipping disabled players
