Use factory to create LADSPA control widgets

Browse Source 
Replace the class `LadspaMatrixControlView` with the factory class
`LadspaWidgetFactory`. The former was a widget that wrapped the widget
representation of a LADSPA control in yet another widget with a layout.
The factory simply returns the configured widget so that it can be
incorporated directly in layouts or other widgets.

Adjust `LadspaMatrixControlDialog` so that it uses the
`LadspaWidgetFactory` instead of the `LadspaMatrixControlView`.
