Big bSDD overhaul for properties and classifications. See description.

* bSDD now supports a couple more args when querying the API.
 * Fetching properties via the classification UI has been removed
 * The bSDD dictionary selector has been merged into the classification
source dropdown
 * The bSDD dictionary selector merged into the property set name
dropdown
 * You can now search for properties in the bSDD directly when adding
properties
 * You can browse properties via groups or classifications (based on
assigned classifications)
 * You can browse properties via keyword (with some limitations due to
the API)
 * You can selectively choose which properties you then want to add.
Only basic support right now.
