#229639 - Composite components doesn't work well with new xmlns.jcp.org namespace

Bug:
https://netbeans.org/bugzilla/show_bug.cgi?id=229639

Description: Composite component doesn't work well with the new JSF2.2 
namespaces placed at xmlns.jcp.org and also doesn't use new namespace by 
using new composite component action.

Impact assessment: Error in the editor using new namespace introduced by 
JSF2.2 - the only workaround would be to use legacy namespace which 
doesn't look well in combination of new and legacy NSs.

Risk assessment: Not much risk. Composite components tries to find out 
suitable namespace and editor uses the new namespace by default and 
tries to look also for library suffix with older namespace.

The fix was written by me, reviewed by mfukala and verified by vriha.

Thanks for the review, Martin.
