Set time-of-day consistently to midnight for until day

A day begins on midnight (inclusive) and ends on midnight (exclusive). A
day as a whole is represented by the initial midnight, i.e. time-of-day
is 00:00.

On load of recurrent appointments (but not events) time-of-day for the
until day is set to 23:59. For a newly created recurrent appointment the
setting depends on the input method: time-of-day is set to 00:00 if
until day is given as a date (day, month and year), but to time-of-day
for the start day if given as an offset (+dd).

The resulting behaviour is only visible in interactive use of calcurse
as proved by the following scenario.

1) Create an appointment with start time 12:00, end time 11:59 (multi
   day).

2) Turn it into a recurrent appointment of type daily, frequency 3,
   until day +3.

The appointment is correctly displayed with two 2-day occurrences three
days apart.

3) Edit the appointment and select Repetition. Accept existing type,
   frequency and end day (now as a date).

The second day of the second occurrence disappears.

4) Repeat 3), but set the end day as an offset (+3).

The second day of the second occurrence reappears.

The inconsistencies have been eliminated, and time-of-day for the until
day is now always 00:00.

Also, until day may equal start day, so midnights should be compared.
