* Added 'RDTimeEdit::Mode' enumeration.
* Added 'RDTimeEdit::mode()', 'RDTimeEdit::setMode()',
'RDTimeEdit::length()' and 'RDTimeEdit::setLength()' methods.
* Fixed a regression in rdlibrary(1) that caused the 'Forced Length'
control in the 'Edit Cart' dialog to be misformatted when the
system was configured to use 12 hour time format.
