Update link to "Developers Website" in Google Play listing

[todorus]

In the current listing "Visit Developers Website" links to the Google Code project instead of this Github one. Since there isn't a link to this project on the Google Code project as well, it has a serious impact on issues bieng reported and developers contributing, as they cannot find the proper project.

As this is a very easy fix with a lot of potential gain, I hope this gets a high priority from the owners of the Google Play Developer account and/or those of the Google Code repository.
