RF-11994 : improve xcss to ecss migration utility

Improvements :
 * handles f:if
 * handles skin attribute in <f:verbatim skin="xxx"/>
 * handles default attribute in ui:style (<ui:style default="...")
 * <f:key f:skin="myProperty"/>

Opened the API (public) for CreateParser / Handler.

Created FilterReader internal class in order to convert a batch of xcss files (with ANT).

Added unit tests.
