Add support for commands iterable on color schemes (#7329)
Browse files Browse the repository at this point in the history 
## Summary of the Pull Request

![cmdpal-set-color-scheme](https://user-images.githubusercontent.com/18356694/90517094-8eddd480-e12a-11ea-8be4-8b6782d8d88c.gif)

Allows for creating commands that iterate over the user's color schemes. Also adds a top-level nested command to `defaults.json` that allows the user to select a color scheme (pictured above). I'm not sure there are really any other use cases that make sense, but it _really_ makes sense for this one.

## References
* #5400 - cmdpal megathread
* made possible by #6856, _and support from viewers like you._
* All this is being done in pursuit of #6689 

## PR Checklist
* [x] Closes wait what? I could have swore there was an issue for this one...
* [x] I work here
* [x] Tests added/passed
* [ ] Requires documentation to be updated - okay maybe now I'll write some docs

## Detailed Description of the Pull Request / Additional comments

Most of the hard work for this was already done in #6856. This is just another thing to iterate over.

## Validation Steps Performed
* Played with this default command. It works great.
* Added tests.
