Emit a critical warning if features are not initialized

Browse Source 
If you forgot to call clutter_init() then you currently end up with a
warning saying that the stage cannot be initialized because the backend
does not support multiple stages. Clearly not useful.

We can catch some of the missing initialization in the features API,
since we will likely end up asking for a feature at some point.
