Block envmap and lightprobe commands from Lua
Replace usages of string.Explode with string.Split
Properly fix env_microphone missing closed captions
Make dedicated server workshop cleanup do it in correct folder
* Was cleaning cache/workshop/ while saving files to cache/srcds/
* This separation helps ME PERSONALLY when running dedicated servers from the client install
Fixed some dupes/saves/demos not loading
* Specifically when they only have a single tag - Dupe, Save OR Demo
Added more decompression self checks
* Removed FastLZ fallback decompression attempt from util.Decompress - I don't think anything out there can actually hit it. Oldest dupes/saves on the workshop already use LZMA. util.Compress used LZMA since 2014
