WebDAV Editor: Allow set no color for calendar
In the WebDAV editor, when I create a new calendar, Evolution shows as color grey box on grey background, which I interpret as transparent/no color. Clicking on the choose color rectangle reveals, that the actual color for the new calendar is black.
Extend the WebDAV editor:
- “Create Calendar” dialogue to show by default the correct color for the new calendars
- to be able to create calendars without colors
- to be able to delete the color of a calendar (just as it can delete calendar-order).
