Undo and Redo Buttons - Beta 7

The app has been able to do undo and redo since the first release. However it was only accessible using the keyboard shortcuts of Ctrl+Z and Ctrl+Shift+Z. That meant that users on touch devices, and users not familiar with keyboard shortcuts were missing out on this awesome ability.

This was a great suggestions from one of our users. If you have a suggestions, please leave some feedback.
