Only update default colors when needed, and update() when it's done

Browse source 
With commit 7c5d5440e5, it became
 possible that `update_colors()` may run without being immediately
 followed by an `update()`. But `update_colors()` creates a new
 `metadata_set`, which means `attr_list` may now contain out-of-date
 metadata indices to the old cleared `metadata_set`.

 With this commit:
 * A `metadata_set` is only cleared and recreated in `update_colors()`
   if default colors have actually changed.
 * A `bool` is returned and set it to `true` from `update_colors()` if
   a color update happened.
 * An `update()` is run if we get a `true` from `update_colors()`.
 * And finally, `update_colors()` is renamed to
   `update_default_colors()`.

 Fixes #291.
