Suggestions for Ribbons

[Lucasharskamp]

There are a couple of features missing in Ribbons which I think would be something a lot of people would want. (To make them more in line with other components) If need be, I can develop them myself and create a PR. But first I wanted to check if this would be acceptable.

1. A RibbonGroupItem / RibbonItem need a Disabled property (boolean), with the same features for it as in, say, Buttons and most other components.

2. RibbonTab / RibbonGroupItem / RibbonItem need a Color property (boolean), with the same features for it as in, say, Buttons and most other components.
   Example:
   

3. RibbonGroupItem needs a Name property (string), same as the one used for RibbonItem

4. RibbonGroupItem and RibbonItem need a OnClick method, since that would make code maintainability easier than going through all the Name properties in a global OnClick event like the documentation describes. (void, Task, void/Task with MouseEventArgs event)
