KYRA: some little debugger fixes
|Reported by:||SF/clemty||Owned by:||lordhoto|
this patch will prevent users from entering invalid values for the "give" and "enter" command, thus preventing it from segfaulting.
also fixes the problem where when entering rooms 53 or 54 without parameter Brandon isn't visible.
if the debugger is reused this way in kyra2 or kyra3, additional checks need to be inserted to make sure it doesn't prevent the user from entering valid numbers in those games
