Style dialog update

* Did most of the visuals in .less files
* Implemented 4 state machine, works great!
* used more of a normal Windows style
* quite willing to do more on the visuals as needed, but I think it works well
I tend to lean against checking in something that isn't used. More bulk to ship, and if we don't proceed right away to integrate it, it may get more and more out-of-date with the code that generated it. OTOH, don't want to lose what you've done creating it, if that involved significant work. And it MIGHT be someone else who eventually tackles this task...what do you think?
