Make creating services - add descriptions

[jesperordrup]

Make it clear which services are available.

When adding a service you are presented with:

For instance, is "Ghoist" this https://github.com/TryGhost/Ghost ?

Consider adding

1. Description
2. Links to homepage and repo

Add a bit more info about what service is being configured in the flow will help

For many reasons you can be interupted or someone else is working on the team adding features. Or maybe just to confirm for you what you're doing.
