Fixed test database path
Changed v_date field in test table definition to timestamp type
Reduced maximum length of double precision type to 18
Tests 001 002 003 006 pass
Test 004 (BLOB test) still needs to be fixed
Test 005 (Transaction) gives the right output but issues a warning
Took the old PHP 3 regression testing framework and rewrote it in PHP.
Should work on both Windows and UNIX, however I have not tested it on
Windows. See tests/README for how to write tests. Added the PHP 3
tests and converted most of them.
