* Added foundation for Bookmark refactor

* Code broken, need to take a break. Issue is Getting bookmark image needs authentication but UI doesn't send.

* Wrote the basic logic to kick start the bookmark migration.

Added Installed Version into the DB to allow us to know more accurately when to run migrations

* Updated all references to BookmarkDirectory to use setting from the DB.

Updated Server Settings page to use 2 col for some rows.
