Adding AR tests for JDBC connections

New connections:

  jdbcmysql jdbcpostgresql jdbcsqlite3 jdbcderby jdbch2 jdbchsqldb jdbcpostgresql

To test you will need the native database installed (if one is required),
activerecord-jdbc-adapter and the specific activerecord-jdbc<database>-adapter
for the database you are testing.

Run the tests like this:

  jruby -S rake test_jdbcmysql
