backup the ATL-based filmDS

we want to get rid of this, but first we need to make an alternative work.
include filmDSATL in the autotools project
switch to new (old) filmDSatl

for now, once the new code is working, we switch back
Don't include QuickTime-headers

QT initialiasation is now done in the resp. plugins
Fixed reverse flags

somehow we added _LIBS to CXXFLAGS and _CFLAGS to LIBADD...
