Handle file-properties for setting eXecutable flag

This commits introduce the feature "urn:AGL:widget:file-properties".

This feature actually only allows to set execution flag to files
of the widget.

Example:
  <feature name="urn:AGL:widget:file-properties">
    <param name="flite" value="executable" />
    <param name="jtalk" value="executable" />
  </feature>
