Subject: [PATCH] widgets: Allow color dialogues to not match the image mode

For some GUI elements, we may not want to restrict
the color options to the image mode (for instance,
grid colors on a grayscale or indexed image).

This patch adds a "user_context_aware" boolean
to GimpColorPanel so it can be passed on to set
the same boolean already in GimpColorDialog.
This allows GUI elements like GimpGridEditor to
optionally give full color choices to users,
independent of the image mode.
