SCI: improved lb2+kq6 patches (new speech state)

adds a third button state to the game menu
this state is "dual mode" (audio+text at the same time)
currently uses the "speech" graphic
CD versions of Laura Bow 2 + King's Quest 6 will now always get patched
SCI: LB2CD patch: remove audio mode reset code

on init/reset the game resets the audio mode to "speech", which would make it impossible to watch the intro using "dual mode"
SCI: readded kq6 stepmother patch for dual mode

SCI: change floodfill to fix sq4 ship taking off

fixes bug #6446
AGOS: Add German Amiga OCS version of Simon the Sorcerer 1.
SCI: change floodfill fix for sq4

behaviour wasn't changed in SCI1, instead it seems that SSCI draws overlays to separate memory and then copies them over. Previous commit caused regression in qfg1vga (funny room)
SCI: workarounds / new bug ids in comments
HOPKINS: Fix bug #6456 - RTL not working.
