- Adds Zotero.Item.attachmentContent property -- works for HTML, PDF, and plaintext attachments

- For PDFs, stop deleting full-text cache file after indexing, and regenerate when getting content if necessary
- MozMill tests

Other MozMill changes:

- Added Cmd-Shift-M shortcut key to open window
- this.controller now available in Zotero.MozMill if passed in from setupModule() with Zotero.MozMill.setController(module.controller);
- Various new Zotero.MozMill methods, including for creating file attachments
