`param works:
* On self
-- if you have ACCESS_TESTER and param you want to change is in in testerparamslist[]
OR
-- if you have ACCESS_MODER or higher
* On NPC
-- if you have ACCESS_ADMIN
* On other player
-- never
Ghosthack solution removes all limitations except one tied to ACCESS_TESTER, which is trivial to disable.
`param syntax is quite different than hardcoded ~param command
- first argument is always 0
- it uses global switch "-p" to define target (if not used, it targets self)
To change other critter param you have to (on 2238):
`param 0 [paramId] [value] -p [targetNameOrId]
Instead of (on TLA):
~param [targetId] [paramId] [value]
