#229773 - JSF from entity classes point to not existing template

Bug: https://netbeans.org/bugzilla/show_bug.cgi?id=229773

Description: JSF generated from entity classes point to template.xhtml 
but there is template.template file in project directory.

Impact assessment: Generated code from JSF Pages form Entity Classes 
throws error in runtime on the index page. It would be visible 
regression in one of pretty favourite feature.

Risk assessment: Almost no risk. Few naming changes to the generated 
files which were tested by QE.

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

Changeset: http://hg.netbeans.org/web-main/rev/2454bc59ffbf

Thanks for the review,
Martin.
