- closes #536, Hanging indent missing in APA citations in Word

- closes #736, bring Zotero up to date with latest CSL revisions - allows citing multiple sources in IEEE and Nature styles, collapse citation numbers, and sort citations by citation number - fixes a bug in the add citation dialog when adding items to the "Multiple Sources" pane, then turning off multiple sources
