2.5.3b release - rough cut

Here is a rough cut of the version which runs on 2.5.3b. We tried two other databases that claim to be compatible with Oracle - one$db (daffodil) and enterpriseDb. Both had compatibility issues. So we forge ahead with patching hsqldb which seems like one of the strongest java databases out there.

Many problems occur - compatibility with SQL - when trying to run Compiere against HSQL. We are addressing them one at a time.
