The mysteriously named AUTOLAYOUT_ENUM had the same value as
AUTOLAYOUT_TITLE_CONTENT, and was marked as "deprecated", so just use
the latter instead. Use it also in xmloff instead of the magic number
1 in places where comments indicated that AUTOLAYOYT_ENUM was what the
1 meant.

Will continue with the other "deprecated" and duplicated enumerators
later. (Or you feel free.)
