poppler-data reviewed, built for rawhide

[Rex Dieter]

fyi, poppler-data review finished,
https://bugzilla.redhat.com/show_bug.cgi?id=507675

and built for rawhide,
http://koji.fedoraproject.org/koji/taskinfo?taskID=1576318

I suppose we could add a dep for it to poppler now (like how it was bundled
with poppler pkgs in previous releases)... or not, it's optional after all.

Alternatively, since it helps certain only certain locales/encodings, could
add it to the appropriate CJK and Cyrillic related lang-support groups in
comps. 

thoughts?
