some whitespace changes

some whitespace changes
rearranged a few cvar definitions to be in more appropriate places

added bitprofile command to report popularity of entity update components
fixed a number of baseline bugs and inconsistencies in the server and client (discovered using bitprofile)
general baseline generation code added (protocol.c)
added freelook cvar and menu option
exterior model capability added (so a model could be visible only when you are using chasecam, needed for visible weapon models)

renamed Sys_FloatTime to Sys_DoubleTime
rewrote win32 Sys_DoubleTime code and minor work on UNIX Sys_DoubleTime
removed most of svc_entitiesbegin/svc_entitiesend code (big entity update protocol improvement planned)
hardware gamma/brightness/contrast support
hardware and software gamma/brightness/contrast adjustable in the menu
gl_lightmode (also known as lighthalf) switchable in the menu
can pick a crosshair in the menu
changed renderer references to r_refdef.vieworg to use r_origin instead
stripped out ancient transpoly code that was not being used

moved some entity_state_t related stuff to protocol.c and protocol.h
made delta compression optional (sv_deltacompress cvar)
removed a lot of cruft
