Switch for all repos

We have updated our GitHub Single Page App. So far we only supported repositories from languages VersionEye already supports. That means we used to read the repository language via GitHub API and if it was one of our supported languages, we showed an active “switch” widget you could turn on or off. Unfortunately, this caused errors sometimes. So we changed the behavior. Now the “switch” widget is always active. You can turn it on in each and every case and VersionEye will try to find a project file in the root of your repository.
