- Custom protocol handler extensions like zotero://select can now not return a channel and the request will be automatically cancelled without throwing an error
- Switched Timeline code to use the stringbundle methods to access timeline.properties
- Even though zotero://select now works properly, switched Timeline to access ZoteroPane directly and call selectItem() (calling toggleDisplay() first to open the Zotero pane if necessary)
- Now getting some localized strings from Zotero ("Date Added" and the short month names)
