Move dependencies to mozbuild
In light of having less dependencies to manually install on Windows the following branch will use mozilla-build for it. It switches 7zip and WIX to mozilla-build. As an aside, this means it works, but we will be dependant on mozilla-build versions.
The branch name is 'move-depends' and resides in my public tpo repo.
