Feature: Pre-programmed scales (as in Novation's most recent firmware)

Would be great to have another setup page or something of the sort in "note" mode which provides a scales shortcut setup similar to how the somewhat recent official update provides. 32 scales pre-programmed in and accessible with one easy button.

I have implemented this on my fork, but I need to do some cleanup work before I submit a pull request.
