Mvc module becomes unit

The module from the Mojavi package creates a confusion with the XOOPS 
module. The concept provides some useful separation, and concepts such as
filters apply at the module level. Renaming this layer as a unit, both 
externally and internally, gives us a clear terminology for the structure:
XOOPS module, then MVC unit, then action.
