Added the global float "intermission" to CSQC defs (in clprogdefs.h).  Intermission was added after the global float servercommandframe, and MUST be added in all CSQC definitions files at this location.  This float is updated whenever the client intermission is updated.

This new global float is part of Spike's CSQC definition, as it exists in his globals as well (albeit in a different order from DP's).
