Hide Format hints when datetimepicker is present

[Ryan J Ollos]

Fields that display a datetimepicker have an adjacent Format string. The string may have had a purpose before the datetimepicker was added (Trac < 1.0), but serves little purpose now. We could hide the strings using jQuery so that the strings are still present for as a no-javascript fallback.

Proposed changes in log:rjollos.git:t12224-hide-datetime-format-hints.

It would be good to add class to the container element in the same way as Hide help links feature in preferences instead of directly hiding hints.
