Lunatic translator: new switch -W(no-)error-bad-getactorvar.

Browse source 
Toggling whether a getactorvar for a global or per-player gamevar issues
a warning or a hard error, the latter being the default.
Also, make it possible to readgamevar/savegamevar per-actor gamevars and
add userdefs member "idplayers" (read-only).
