The calendar now verifies that the user can't input invalid date ranges,
i.e. date ranges where the end is before the start. The UI elements do
this implicitly, by adjusting the values when changing the dates in an
illegal way (e.g. when picking an end date that is before the start
date, the end date will change to the start date).
Previously, we had two versions of MonthListModel for the AddEventDialog
and the DatePickerDialog. Now, a unified version is in the Calendar.h
file, which can be used easily by anyone. Since that model and the
MeridiemListModel weren't used anymore in the AddEventDialog, I have
also removed them from there.
The user can now save, load, and view calendars. A calendar is made up
of an array of events which are saved in a JSON file. In the future we
should implement the iCalendar standard instead of using a custom
format.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
Most of the models were just calling did_update anyway, which is
pointless since it can be unified to the base Model class. Instead, code
calling update() will now call invalidate(), which functions identically
and is more obvious in what it does.
Additionally, a default implementation is provided, which removes the
need to add empty implementations of update() for each model subclass.
