Refactored date time delegates to use a simpler default editor via a
default item editor factory for QDateTime values, the editor is a
standard QDateTimeEdit with a format that includes seconds and renders
assuming the time is UTC.

QDateTime items for the edit role of date time fields, and formated
date time strings including seconds and assumed as UTC for the display
role.
When RR73 is received we log the QSO, turn "Call 1st" OFF, and call CQ again.

Improve layout of log view tables by resizing to contents.
This change incorporates a reorganization of the GUI code with
widgets, validators, models, and item delegates being moved to

CandidateKeyFilter classes to allow them to work with constant model
pointers for both referenced and referencing models.
