Adds automatic pre-release update prompts

This update adds the pre-release update preference from 0.5.3. Regardless of your preference, whenever a pre-release workflow is installed you will see pre-release updates. This will help to ensure that everyone who is willing to test stays up-to-date with the latest fixes and improvements.

So, if you download a pre-release update you don't need to also change the preference, you'll automatically see pre-release updates until you install an official release again:

	Official release installed	Pre-release installed
Normal update channel	Prompts show official releases only	Prompts show official and pre-releases
Pre-release update channel	Prompts show official and pre-releases	Prompts show official and pre-releases
