- Fixes #1063, Duplicate item with tags broken in Sync Preview
- Added better purging of deleted tags
- Added local user key before first sync
- Add clientDateModified to all objects for more flexibility in syncing

- Additional trigger-based consistency checks
- Fixed broken URL drag in Firefox 3.5
- Disabled zeroconf menu option (no longer functional)

Developer-specific changes:

- Overhauled data layer
  - Data object constructors no longer take arguments (return to 1.0-like API)
  - Existing objects can be retrieved by setting id or library/key properties
  - id/library/key must be set for new objects before other fields
- New methods:
  - ZoteroPane.getSelectedLibraryID()
  - ZoteroPane.getSelectedGroup(asID)
  - ZoteroPane.addItemFromDocument(doc, itemType, saveSnapshot)
  - ZoteroPane.addItemFromURL(url, itemType)
  - ZoteroPane.canEdit()
  - Zotero.CollectionTreeView.selectLibrary(libraryID)
  - New Zotero.URI methods
- Changed methods
  - Many data object methods now take a libraryID
  - ZoteroPane.addAttachmentFromPage(link, itemID)
- Removed saveItem and saveAttachments parameters from Zotero.Translate constructor
- translate() now takes a libraryID, null for local library, or false to not save items (previously on constructor)
- saveAttachments is now a translate() parameter
- Zotero.flattenArguments() better handles passed objects
- Zotero.File.getFileHash() (not currently used)
