Added dbid to all stored objects
Added new type to db
Major changes to model

* A schema is no longer needed, objects list the data that should
be saved, and the cursor is smart enough to parse it.
* Changed name of "ScanObject" to "ScanParent" for "Parent of all things scanned under this name"
* Scan Parent objects are now saved in the database. The model now properly queries for them when it needs to
* "Removes" now work properly, and "deleted" data is now never returned by the model (it was before, and this was a bug)
Fixed bug with view displaying previously deleted content

It couldn't handle the idea of displaying *nothing*
Fixed duplicate file attributes not displaying correctly
cursor queries now support filters
Re-added delete functionality
