fix insert tests on oracle
[sqlite3] setup native types + make sure tables accepts table_name as well
Conflicts:

backported for #340
call #configure_connection on #reconnect! if adapter has one (#351)
this still won't resolve since auto-reconnect happenson the (Java) JdbcConnection side and has no notion of the adapter currently
... probably will need a refactoring in 1.3 to get this right
re-arrange (and document a bit) JdbcConnection code
prepare for 1.2.9 - the "really" last 1.2 (due broken oracle inserts #348)
