Improved error message with database Node can't be found
Removed extraneous comment
Fixed issue with non-JDBC/default datasources where the database element from the MoquiConf XML file was required in the EntityFind.iterator() method
Fixed issue in tableExists so that table exists check happens in a separate transaction, otherwise Atomikos for some reason doesn't return closed JDBC Connections to the pool (ie doesn't delist them)
Improved DataSource resource name for XAResource, etc
Added some commented code useful for tracking down connection pool issues
