Create new color picker & color field

[manuelmeister]

While trying to create a color field on the campCollaboration to be able to differentiate between users with (accidental) same colors, I realized that our colorpickers were not able to handle null values. I thought it would be best to implement the new colorpicker using the EParseField.

Now the the parsefield needs 3 different value types:

• SerializedValue: this is the type(s) that can be provided as v-model
• InternalValue: this can be any type of your liking, e.g. an object
• StringValue: this is the string (value) that is displayed in the textfield

Please replace the existing usages of the old color picker with the new one, I would prefer not to have two different versions at the same time.

The validation message on invalid format in the old picker was "Das Format von entity.null.fields.color ist ungültig", while the new picker outputs "Could not parse #asdfas as a color. Missing a plugin?"

Using only the keyboard, I cannot open the dialog in the new colorfield. The swatch button isn't focusable for me.

The old api-colorpicker apparently happily saves #asdfas as category color, and the category color input isn't displayed anymore from then on. Could we make sure to fix this in the new picker?

@carlobeltrame sorry this is not yet fully reviewable. Of course my goal is to replace the other colorpicker and have it completed to parity with the current one. I'll notify you when I'm ready.

yes should be fixed

@carlobeltrame I figured, I'd rather have a separate color field that has no popup, just a text field and add a separate component with the picker. As soon as I fixed the tests, I'll replace the old color picker with the new one.

One question only.

Didn't look through all the code, yet. But purely from user testing seems to work as intended 😃

@usu can you have a look at it again?
@carlobeltrame it is ready now to be reviewed 😉
