Particle system functions renamed a bit, a few other cleanups in that area. Console handling tweeked. Better rules for subconsoles and plugins. Commands are coloured if it'll be execed, which should help reduce occurences of chat being commands. tab compleation tweeked, partial compleation no longer changes the suggestion. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@895 fc73d0e0-1445-4013-8a0c-d673dee63da5
