Adapt the code for the new automatic button

It's now used instead of the 0 item of the ValueSet,
but part of the code wasn't adapted:

* Set the correct text (Automatic/No Fill) depending on
  the command.
* Hide the button for frame/line colors, since there is
  no such thing as "Automatic" color.
* Remove the selection and the status update code of the
  0 item.

Update the status only after colors load

This is required to get the current color
selection on the palette upon opening.
