use an imagemap for the "fork me on github" ribbon

ivanov · ivanov · commit 920557fdd762 · 2012-11-09T19:52:22.000-08:00
Right now, the ribbon on the front page blocks out the possiblity of clicking on the "Index" link, because the "Fork me on Github" link is on top of it. I've rectified this by providing an imagemap, which only makes part of the image clickable as a link. I've verified that it works under Firefox, Chromium, and w3m. I have also moved the ribbon from being only on the front page, to appearing on all pages, since that has the potential of inviting contributors more actively, as most people won't spend much time on the index page, once they are actually using matplotlib, whereas they will be peaking at the gallery, as well as the api docs, etc. I got the numbers for the ribbon from here: susestudio/studio-help#20, but then adjusted them so that the full upper left triangle would be clickable, and not just the ribbon.
