Baseline v1.2.1

The repository hosting SwiftDialog changed from Bart Reardon's personal github to an organization github. This broke the automatic installation of SwiftDialog for configurations which did not include Installomator labels. This update fixes that problem by updating the URL to the new value, and future proofs it by using -L for finding the latest version in case it moves again.

If you are using Installomator in your Baseline configurations, then you do not have the problem described above and should not feel like you need to update your Baseline deployments.
