[wix-users] Show a message when no features are selected

[John Cooper]

Use of Feature state before CostFinalize is going to be unreliable at best.  When processing Feature states for UI, there is a very narrow window where those states have any meaning.

Your testing will need to be exhaustive to catch the edge cases.  Upgrades, repairs, and patching can be a bear with only a subset of Features installed.

I have one Feature-driven MSI.  There is a reason why I am ripping it apart into 6-15 separate MSIs and wrapping with a custom bootstrapper.
