Let me have ISO 8601 dates (YYYY-MM-DD) in the event editing dialog
Semi related to #92 but separate issue nonetheless:
My mind can't quickly parse anything other than the YYYY-MM-DD standard format, ISO 8601. I would really like to be able to use it in GNOME Calendar no matter what the system locale is. With other date formats, I can never easily tell which part is the month and which part is the day (especially as I keep alternating between English and French systems), and my eyes have to parse the whole thing evertime... whereas with ISO 8601:
- There is no confusion
- If I want to know the day, my eyes just have to jump to the last two digits of the string no matter what, and that's extremely efficient for me.
- It is also much easier to click roughly in the end of the GtkEntry to set the cursor in a way I can delete and rewrite the date easily (since I don't use the date picker popover widget, unless I don't know what date I'm looking for).
