[hr] #177259 - update Java EE 6 XML schemas

https://netbeans.org/bugzilla/show_bug.cgi?id=177259

As described on http://wiki.netbeans.org/JEE6ThirdPartyComponents page 
most of the Java EE 6 XML schemas bundled with the NB68 are not up to 
date. Once the Java EE 6 is final all schemas should be updated - 
current patch is based on glassfish-v3-b73-11_19 which should contain 
final schemas which will hopefully not change again. Patch provides new 
schema versions and alters build script for schema2beans generation.

Depending on day of integration of this fix and availability of 
GlassFish v3 RC1 the schemas may still change but that should be minor 
change from NB code based point of view.

Milan Kuchtiak is testing the patch.

Thanks,
-David
