Title: Microsecs

first throw at support for microsecond resolution, comes with a major improvement of the tests for TIME, DATE and DATETIME.
TIMESTAMP with fractional seconds is not supported with tests yet as the test here fails sql-syntactically (maybe it still just works...).
At the very least, this can be built upon.
