compatibility option for old size of small caps (bnc#691473)

Version 3.2 had 66 as the small capitals size percentage, later
changed to 80 (see e.g. http://openoffice.org/bugzilla/show_bug.cgi?id=1526).
This however can destroy layout of old documents that rely on the old
size. So for backwards compatibility the old value is used if either
the .odt document has an option enabled or does not have the option
at all (meaning it's an older .odt document). There's unfortunately
a period when the new value was already in effect where this change
can break those documents :-/.
