Automatically determine interpretation from mime-type when it's empty

[Siegfried Gevatter]

Several of our client APIs (python-zeitgeist and libzeitgeist) currently support guessing the subject interpretation from the mime-type.

I think it'd make sense to move this directly into the engine. So, if a subject is inserted with an empty interpretation (which seems to be allowed currently), we'll try to determine it from the mime-type.

This will avoid duplicating the mime-type mappings in different bindings. It'll be even more useful for clients using the D-Bus API directly (such as GTK+).

I had an extension for kde users that depended on kio to get the interpretation of an based on the mimetype.
My questions before this is hacked:
1) Is there a way to do it cross platform so we dont need to depend on any GNOME or KDE libraries to do so
2) Should we do it as an extension that hooks into "Pre Insert Event" or hard code it into the engine.

This is nothing new, just the existing code from Python/libzeitgeist.

Sure, we're just looking up the "subject mime-type" field in a
mimetype->interpretation dictionary.

Don't see why we would overcomplicate it with an extension. Either we
do it, or we don't, but we don't "maybe" guess mime-type, that's just
confusing API users who want to rely on the feature.

Sorry I thought the other way round where we get a file without a mimetype
then guess the mimetype
