[FEATURE] Advanced undo/redo support

[makuke1234]

Is your feature request related to a problem? Please describe.
The editor should support undo/redo

Describe the solution you'd like.
I'd like the editor support infinite state undo/redo. When the user undoes something and write something new then when undoing again the users should be able to select which redo they want out of all possibilities.

Describe alternatives you've considered.
Just do a normal undo/redo system, but that would be lame :/
