Put basic image metadata into tab.
Update FLVC's MODS class to 8e00c13
Put subjects into a known array key.

The FLVC MODS class puts subjects into an undifferentiated array key
(just an incremented '$i').  This modification puts it into a key
called 'mods:subject' so they can get picked up in the summary
tab view.
Put MODS creator, contributor, subject, date in summary

As of this commit, 'creator' and 'contributor' are not labeled keys in
the $mods_array array, but subject and date are.
Remove FLVC-specific fields from MODS array
