Sentry Buster fixes

Valve did a horrible hack job on a lot of the MvM models, and the Sentry Buster in particular is really bad. Jarate effects won't show up on the top half of the model, and uber effects won't show up at all. There's also no red team skin at all, though that doesn't particularly matter.

This mod fixes some of those problems.

Note about sv_pure

This mod will not work on sv_pure servers (including Valve servers). It will only work on servers that don't enforce sv_pure on the files that are modified.

Files modified

I edited materials/models/bots/demo/demo_buster.vmt to make the yellow jarate tint apply correctly to the Sentry Buster model.

I decompiled models/bots/demo/bot_sentry_buster.mdl with Crowbar and modified it to have 4 skins instead of just 1 (red team, blu team, red invuln, blu invuln), then recompiled. Uber effects now show up correctly on the Sentry Buster model.
