Abstracted the DB layer for use by Zotero utilities

Browse Source 
All the former Zotero.DB methods are now part of an instantiable Zotero.DBConnection object, and Zotero.DB is just one instance of it. Utilities can create and access a new SQLite database within the Zotero data folder by instantiating the DBConnection object:

this.DB = new Zotero.DBConnection('myutility');

Utilities have access to everything the DB layer provides, including automatic backup and restore of databases. Utility writers are on their own for schema management, at least for now.

Also:

- Cleared non-English DB restore localized strings after change.
- Disabled shutdown observer in Zotero object after moving DB backup code to DB layer
