Task: Add github project as "website"

[aheusingfeld]

Please add the github URL "https://github.com/gshakhn/sonar-intellij-plugin" as the project website in the plugin metadata here: http://plugins.jetbrains.com/plugin/?idea&pluginId=7168

This way the project URL becomes clickable in the plugin repository thus people have no effort to directly browse to the project homepage and therefore the chances are that more people might possibly contribute to the plugin.
Thanks
