addresses #214, add footnote support to word integration
- the third icon on the Zotero Word toolbar is now reserved for "Document Options," which, for now, means on the selection of styles
- the Document Options window will, for now, appear the first time you create a citation. the default style probably belongs in the Scholar preferences window.
- you can now generate citations in both footnote and in-text citation formats. you can't yet switch between them on the fly, but that should be coming soon...
- Ibid is not yet implemented. again, coming soon.
closes#4, Make printable version
- moves functions for creating and deleting hidden browser objects to scholar.js (from ingester.js), since these are necessary for printing as well
- allows saving bibliography in HTML or printing bibliography. style support is not yet complete (pending finalization of 0.9 version of CSL specification).
