modified test slide
Cosmetic and functional tweaks to sample slides.
Keeping Dryad links in the same window (from home-page slides)
Added a static page for per-journal policies (should probably be a dynamic list).
Cleanup of table margins (hiding "shim" row)
Adding a static page with the 2013 membership form (TODO: migrate its #ds-body and inline CSS to a proper DSpace page)
Restored original formatting of Integrated Journals table, and abbreviated values.
Merge remote-tracking branch 'origin/trello-34-homepage' into dryad-master
