GLI showing extracted namespaced metadata

[kjdon]

Currently if you use something like EmbeddedMetadataPLugin, you gets lots of metadata like File.FileType, JFIF.JFIFVersion etc.

Because this has a namespace, it does not show up in GLI as extracted metadata. Doesn't show up at all.

Plan: store these metadatas as ex.File.FileType, then modify GLI doc.xml skim file method to look for items with no namespace or items with ex. namespace as extracted metadata.

They will go into the gdbm database as File.FileType though, not with ex. - no ex. will go to database.
