[Feature Request]: Ability to merge KryptonRibbons

[PWagner1]

Originally from @Tape-Worm

The ability to merge ribbons.

The system I outlined in item number 1 relies on being able to display and use ribbon tabs dynamically. In order to do this, I have to merge the contents of one ribbon into another. I have added code to my application that allows the merging and unmerging of multiple ribbons into the the main ribbon. That code is located here (feel free to use this if it helps).

Again, the DevExpress ribbon has merge/unmerge functionality as well, and it's really handy in scenarios like this where you don't know what you're going to get.

I have these things set up as a separate class right now, but it'd be really nice to have something like this out of the box. Plus, you guys would be able to handle potential issues that I can't account for.
