Title:  Dynamic field updates should pass OldValue to Event and History

Dear all,

currently the value prior to an update of a dynamic field can only be recalculated from history which is fairly expensive.

Supplying the "OldValue" as part of the TicketDynamicFieldUpdate_* event allows an event handler to react on certain _changes_ in value (e.g. increase, decrese) without digging into the history.
Recovery from history again is eased by adding the OldValue as an extra item in the "Name" field.

Somehow my GitHup repo is out of sync with the orginal otrs repo; the commit I refer to is the one from January 27 (1 ahead of upstream/rel-3_3).

best regards,
