Add seasons’ relation, functions, and admin section Seasons have a color to show on the calendar. I need them in HTML format (e.g., #123abc) in order to set as value to `<input type="color">`, but i did not want to save them as text in the database, as integers are better representations of colors—in fact, that’s what the HTML syntax also is: an integer. I think the best would be to create an extension that adds an HTML color type, with functions to convert from many representations (e.g., CSS’ rgb or even color names) to integer and back. However, that’s a lot of work and i can satisfy Camper’s needs with just a couple of functions and a domain. To show the color on the index, at first tried to use a read-only `<input type="color">`, but seems that this type of input can not be read-only and must be disabled instead. However, i do not know whether it makes sense to have a disabled input outside a form “just” to show a color; i suspect it does not. Thus, at the end i use SVG with a single circle, which is better that a 50%-rounded div with a background color, even if the result is the same—SVG is intended for showing pictures, which is this case. 2023-08-16 18:15:57 +00:00			`-- Revert camper:add_season from pg`
