Hedgeroid: - Updated assets - reworked team management in a room - lower engine quality (for now) - added focus/disable states for spinner and button graphics


------------------------------------------
-- RACER 0.5
-- map-independant racing script
-- by mikade
-----------------------------------------

-----------------------------------
--0.1: took all the code from crazy racer and scrapped most of it
-----------------------------------

-- Removed tumbler system
-- Removed extra adds like boosters etc
-- Added experimental waypoint placement system
-- More user feedback
-- Reduced race complexity limit to 5 waypoints
-- stop placement at complexity limit reached and end turn
-- guys dont keep racing after dying
-- invulnerable feasibility
-- reverted time keeping method
-- reduced feedback display time
-- colour-coded addcaptions
-- cleaned up code
-- support for more players properly added
-- tardis fix
-- remove airstrikes

-- i think the remainder 0 .456 sec of the tracktime isnt getting reset on newturn

-- update feedback

-------
-- 0.2
-------

-- allow gameflags
-- extend time to 90s
-- remove other air-attack based weps
-- turn off water rise for sd

-------
-- 0.3
-------

-- prevent WP being placed in land
-- prevent waypoints being placed outside border

-------
-- 0.4
-------

-- update user feedback
-- add more sounds

-------
-- 0.5
-------

-- fix ghost disappearing if hog falls in water or somehow dies
-- lengthen ghost tracking interval to improve performance on slower machines
-- increase waypoint limit to 8
-- allow for persistent showmission information
