Imoen Found Gorion's Body 1 Dialog Fix

After finding Gorion's body at the beginning of the game and taking the
note from his remains, if you drop the note before Imoen has a chance
to initiate a conversation with you, she'll constantly try to talk to
you, but only bring up options from player-initiated dialog.

Fix removes variable check from dialog conditions.  Possessing the
scroll is necessary to set the X#IMGBODY variable anyway.
