A nice improvement to get TkSheet 7 working. For the most part, users should just experience a bit smoother operation, no major feature changes on the front end. Developers should experience fewer explicitly listed dependencies. Bumped from 0.50 to 0.60 to illustrate the internal structural changes to handle TkSheet 7.
