Proposed structure for the utility classes

The proposed structure is :

-each module in mapfaces should contains FacesXXXUtils.java with others utilities classes if needed, this class contains only related methods with Java Server Faces dependencies this is to avoid the same names of Utils class in the project.
-the core module contains the main class FacesUtils that is the parent class of all FacesXXXUtils classes.
-XXX is the name of the module for example FacesMapUtils or FacesWidgetUtils

To carry out that we need to cleanup and extract all faces methods included in utils sub-classes and regroup them in each module.
