Minor code fixes via LuaLS diagnostics
It's mostly usage of non existent globals or function arguments
Fixed a regression with env_sky + other editors inherit map values now
MInor adjustments
"Server" menu bar option
Making those settings more visible to the average player.
Also made all the options grayed out consistently with their ability to function at a given moment
Don't record certain pointless convars/commands in demos
Probably a lot more of these need doing
Fallback menu for when menu.html doesn't exist
Should also be used on x86-64 when chromium doesn't launch for whatever reason.
