Update to playtest_beta

• Ported most utilities to Linux The only utilities that have not been ported are HLMV and faceposer. Please report any issues with these ports in #beta-reports. Certain tools may be a bit slower to startup due to game mounting tasks, working on resolving this entirely.

• Changes to vrad:

  • Improved vrad's performance significantly in some scenarios. A fast compile of a test map went from 24s -> 17s with changes to the RNG code. On a final compile on this map, it went from 2m 20s to 1m 35s with the optimized RNG code.

  • Added -noao to disable AO completely. On a fast compile, -noao caused compile time on a test map to go from 17s -> 4s On a final compile of this test map, excluding AO reduced compile times by about 22s

  • Added -aosamples to tweak the number of samples made by the AO code. Final compile uses 32 by default, fast compile uses 16 by default. If you want a really fast compile please just disable AO entirely.

  • Added -nosoften to expose some internal flag, it disables some light softening code
