- Add Zotero.Libraries.isEditable(libraryID) (currently unused)
- Addresses #1444, Attachment arrow/count persists after delete, for items (problem probably remains for collections)
- Dragging PDF favicon or link or clicking Create New Item from Current Page when viewing a PDF creates a top-level PDF -- this is a temporary solution that allows "Retrieve PDF Metadata" to be used until it can be run automatically
- Allow PDF child snapshots to be dragged out of parents
- Dragging a link to a collection now creates parent item and child snapshot
- ZoteroPane.newItem(), addItemFromDocument(), addItemFromPage(), addItemFromURL(), and canEdit() now all take an optional row parameter
