End of Google Summer of Code

This is the last release of Emacsy that will be done under the auspices of the Google Summer of Code 2013. I'd like to thank Google, Ludovic Courtès, and the GNU Project for helping to make this happen. This release contains major changes to the window system, which is illustrated by the emacsy-webkit-gtk that now has three demos. Each demo features a different level of integration: 1) easiest integration, 2) demo has support for multiple buffers, and 3) demo has support for multiple buffers and windows.
