First extension for RichConnection

[muuki88]

This is the first part to customize java.sql.Statement creation. Next step would be to allow something like this.

tx.select("SELECT * FROM table01") { row =>
   // process row
}  { stmt => 
   stmt.setFetchSize(Integer.MIN_VALUE)
}

or with ordering

tx.select("SELECT * FROM table01") (
 customize =   { stmt => 
   stmt.setFetchSize(Integer.MIN_VALUE)
 },
 block = { row =>
   // process row
})
