OPENJPA use Locale.ENGLISH for toLowerCase and toUperCase where possible

* we now use fixed english Locale for 'framework parts' which are by spec portable
* we do NOT yet use a fixed Locale for anything related to column or table names!

ported over from trunk
txs to Kaloyan Spiridonov for the catch!
