Web: Fix wiki statement about not being able to import QFG4 to itself

[lwcorp]

​https://wiki.scummvm.org/index.php/Quest_for_Glory_IV states "nor can a character be imported to the same game that was just completed". But one of QFG4's most notorious cheats is doing exactly that. i.e. it's infamous in the series for allowing such an import without any requirements.

ScummVM did add a minor requirement of its own - having to rename qfg4-XXYY.sav to qfg3-XXYY.sav but other than that it's fully importable into itself.

While even in the original engine any points (except Strength) above 300 get reduced to 300, it seemed ScummVM itself took action to remove the cheat factor by removing all of QFG4's own magic spells while importing from the same game.

Could you therefore please remove the wiki statement about not being able to import like that? Better yet, mention to change 4 to 3 as shown above.
