Spoike 230ce4e0a0 updated mapcluster mode a little, should be more robust now. also supports cross-server events. 
added option for softer/wider lines.
attempt to use hardware cursors in windows. provide api for csqc to specify its own.
cl_downloads cvar blocks all automatic downloads.
QUAKETC: new compile-time setting. if defined lots of stuff will be disabled including built in menus.
remove spam from log files.
try to get the webgl port to complain a bit more reliably when webgl is not usable.
