Merged V3.0 to HEAD

12185: Fix 3.0 SP1 installation on non-Oracle databases. Removed creation of indexes in AlfrescoPostCreate-2.2-MappedFKIndexes.sql that were also in AlfrescoPostCreate-2.2-Extra.sql
  12186: Performance improvements to HibernateNodeDaoServiceImpl
  12188: Multi user tests: enable graceful web script recovery on optimistic locking failure (...)
  12191: Improve Javascript execution performance in Web Scripts & Improve error presentation (...) thrown by JavaScript
  12192: Share performance improvements: stop AbstractFeedGenerator from 'choking' the repository with too many web script requests
  12193: Multi user testing: don't suppress all exceptions during Wiki Move.
  12194: Multi user testing. Don't suppress all runtime exceptions in script site node object.
  12195: Multi user testing. Convert User bean object to use a retrying transaction so that optimistic locking failures are handled.
  12196: Multi user testing: Configuration changes to support concurrent access by 20 users
