NSIS improvements (#1692)

* Much better, but still broken

It crashes with two custom pages after one another. (So when the service should be installed).

* Fixed the problems and finished the NSIS installer.

Also ignored some of the artifacts.

* Added changes to CI for setup building.

Consolidate building and fixed git error.

Small CI fixes.

Move UX repo to SourcesDirectory

Fix stupid checkout <> clone error.

Fix typo in PowerShell command.

Artifact publish tasks can not have wildcards.
