TextPlugin issue with .from() and oldClass

[joeworkman]

If you use the `oldClass` option with a .from() tween with the TextPlugin, the animation does not work properly. The entire line simply displays all at once. Again, this only happens when you defined an oldClass inside of the from tween. It works inside of the `to` tween just fine. I updated one of the default demos to illustrate the issue.

Good catch, @joeworkman! Thanks for pointing that out. It should be resolved in the next release which you can preview at: https://assets.codepen.io/16327/TextPlugin3.min.js
