* This fixes the registry path
What's happening is the console is writing the Forcev2 setting, then the v1
console is ignoring those settings, then when you check the checkbox to save
the v2 settings, we'll write the zeros out. That's obviously bad. So we'll
only write the v2 settings back to the registry if the propsheet was launched
from a v2 console.
This does not fix the shortcut path. That'll be the next commit.
* Fix the shortcut loading too
fixes#2319
* remove the redundant property I added
* add some notes to the bx.ps1 change
* Try createing a script to only build the current working directory
Inspired by #2078.
I wanted to use this for WindowsTerminal, but I can't generate the
resources.pri from just building WindowsTerminal. Maybe @dhowett-msft has
some ideas.
* Cleanup for PR
* fix some bugs with building outside a project directory.
* PR nits
