HM3 Undo feature now live

I've updated the main HeroMachine 3 Alpha application to incorporate the "Undo" feature I mentioned yesterday. Testing has revealed it doesn't cause the Apocalypse, so we're good to go. Please let me know if you have any issues with this release.

For those who missed the post yesterday, this is the new "Undo" button:

It'll undo until there's nothing else to undo. Color changes, scaling, rotation, moving an item with either the mouse or the transform buttons, alpha changes, deletions, additions, "color all skin/hair", "Clear All", you name it, you can probably undo it, except for transformations using the "All Items" grouping, since I'll be changing how that works in the relatively near future.

Hope you like it!
