    Bump API version to 3
    
    The project has been renamed from Gtef to Tepl. But it's still the same
    git repo with the same history and the same tags. Setting the API
    version to 1 would be confusing, because there are already git tags for
    the 1.x.y and 2.x.y versions. Also, it's far less confusing to have the
    major package version being equal to the API version.
    
    The package version is set to 2.99.0 because 3.0 is not yet released:
    2.99.x are the alpha/beta/rc versions, and 3.0.x will be the stable
    version released in September.
