Taken from Portal2 code.
feat(sv_allow_mobile_portals): Added `sv_allow_mobile_portals` doesn't
really work, most of it is not implemented yet.
feat(sv_autojump_): Added `sv_autojump_` does what it says - auto jumps.
fix(d1_canals_01): Fix crash when vortigaunt charges your suit.
fix(CRagdollPropAttached): Check if `pRefObject` is nullptr so we can
feed a combine apc to a barnacle.
Fixes portals getting stuck in objects.
fix(Portal Trace Filter): Can shoot through cubes now.
refactor(Soundscape)!: Updated to the CSGO Version.
chore(Copyright): Remove dates and unicode characters.
fix(crowbar): Fix crowbar not hitting through portals.
chore(util): Added UTIL_GetNearestPlayer function from valve developer wiki.
Made this a month ago and didn't really test anything now.
A lot of useless portal ray traces.
