Separated the VRAD calls into two sequential while using HDR (-ldr and -hdr) instead of -both
Model browser is now created once per session

Added a new template mod that replaces the old 'advanced' source . This template has options for teams,classes, sprinting, prone, stamina, etc.
Added shader source; fxc.exe, psa.exe and vsa.exe must be placed into the dx9sdk\utilities folder and you must modify materialsystem\stdshaders\buildsdkshaders.bat to set your paths.
