Does it make sense to add a new method name for this?

We should also add support for querying available plugins. Compiz itself
is the only one that can determine available plugins as it depends on
currently loaded plugin loaders. We'll need a new method for that
anyhow. This method would need some changes to the core to work but I'll
take care of that sometime in the next couple of days.

You're patch looks good otherwise. We just need to decide if we should
use a new method name or not. To me, it makes sense to use a new method
name.

Thanks,
