Now it is possible to define a custom colour set per bone group. This allows rigs to look consistent across different computers with different themes. As such, the bone-groups buttons have been reshuffled to present the settings in a better way.
Colour sets are now selected from a menu with descriptive names, instead of using a slider. Choose the 'Custom Set' entry to use a custom set of colours for the active group. The sets of theme colours have been retained, and can be used directly, or as the basis for a new custom colour set (when any one of the colour controls is touched).
For bone-groups that haven't had any custom colour set used yet, a default 'test' set is used. This uses bright versions of the RGB colours.
