fteqw/engine/common/fs.c
Spoike 8efd3f15be fix qcc typeinfo limit. 
changed triggers so that some can be used in demos.
demo_setspeed is now a command, in order to handle 100 being 1:1 speed.
avoid weirdness at the start of demos.
only display flag columns if someone grabbed a flag.
reworked internal server browser. now has a filter, sorts by addresses, preserves sort columns,
