DATAJPA-316 - Added build profiles to build against Hibernate 4.1 and 4.2.

Upgraded to Spring Data Build 1.0.2.RELEASE along the way. Needed to upgrade to HSQLDB 2.2.9 as Hibernate 4 doesn't work with HSQLDB versions 1.x. Set up OpenJPA test run to still use HSQLD 1.8.0.10 as OpenJPA does not work with HSQLDB 2.x. *sigh*
