Files that aren't in the UTF-8 encoding were breaking the import dialog.
This tries to guess the encoding of the file before processing it, based
on the Byte Order Mark (BOM), and converts it to UTF-8.
Fixes#1243
When dragging and dropping events in week view during the week of
daylight savings time switch, events were off by one hour. This fixes this
behavior by using the util function gcal_date_time_add_floating_minutes.
Fixes#1198
In the import dialog, start and end date-time fields were being
incorrectly displayed, not considering the local timezone and the
24-hours vs 12-hours format used by the user. Also, the libical
already deals with the case in which events do not have the DTEND
field, simplifying the implementation.
Fixes#1175
In case the location is an URL, it is irrelevant to display the full
link,
as it is not clickable. So, this shows the meeting service provider if
it
is known or reduces the text in the tooltip, preventing it from covering
other information in the calendar.
Closes: #1232
