Spoike ce3c561cfe CSQC is standard now, and secure via the same md4 as a map currently has. 
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.
