In order to register plugins, which aren't statically defined since you
must explore a library and load a specific one, a small refactoring of
the factory was needed.<br>First step was to create a complete separate
Factory (called LadspaFactory), which stores LadspaWrapperCreator
objects and returns a new LadspaWrapper object.
<br>With this patch, a new CLAM::Registrator has been added, supporting class objects.<br>So now, every call to the registrator actually registers it twice, one with the old and the new one.<br>With the new one, notice that a call for Create of the class.
