Shortcut key handling improvements:

- Fix Cmd-Shift-Z on Fx3/Mac when Zotero pane is open
- Don't override Redo on Fx3/Mac even if the override pref is set, since it can coexist -- this lets Redo be used within textboxes
- Ignore Zotero shortcuts (other than master shortcut) when Zotero pane isn't focused

This needs testing.
