Remove DesignTimeStyleHelper #1352
Description
We have a DesignTimeStyleHelper project in our solution, which as far as I can tell was intended to be a standalone application for quick iteration if the dialog UI outside of VS. I say "as far as I can tell" because it's never worked in the time I've been here - I've gone back to release 1.0.18 and it still doesn't work.
The problem with this project is that it's not going to be easy to update with the changes from #1346, especially as it doesn't work.
@jcansdale has asked for something similar, but for both the GitHub pane and the Dialog. #1346 should make this easier, but it will likely share none of the same code, as DesignTimeStyleHelper is very much tied to the non-MVVM way of doing things.
Given that nobody seems to have used this project for over a year, I vote for dropping it and building a new application that can display both the GitHub pane and the dialog in the same application, based on #1346. Any objections?
