#229573 - Default xmlns.jcp.org NS of components is marked as invalid

Bug:
https://netbeans.org/bugzilla/show_bug.cgi?id=229573

Description: Custom created tag using @FacesComponent is market as 
invalid by the editor, it doesn't recognize the new 
http://xmlns.jcp.org/jsf/component namespace.

Impact assessment: Error by using custom components of JSF2.2 which 
doesn't have any workaround.

Risk assessment: No risk, whole change is only about changed string of 
the namespace.

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

Fix: http://hg.netbeans.org/main-golden/rev/ef5cb15f6eb5

Thanks for the review,
Martin.
