Better UX for launching a token

[lsaether]

During user testing, one of the most prominent pain points for users was the launch page. The fields presented nakedly were confusing to them, and they didn't know how to proceed without guidance. To better enable user friendliness we can reduce the launch page or provide more information about what to fill in for it. There are three options:

1. Provide information tooltips for each field which explain what that field is for and how to fill it in.
2. Break out the launch page into multiple wizard steppers, each one providing information for that step and some fun / encouraging words.
3. Reduce the launch to just the essentials: name and symbol. We then push the rest of the information to be added later after the user has had a chance to explore the ecosystem and see what others have done.

Mostly implemented with #91 StepWizard

I just added helper text popovers for each step (on a new branch).

What is still missing:

• form validation for the different steps
• more fun stuff
• some encouraging stories while you are waiting for deployment to complete
• more intuitive entry for the tags
• nav / progress component

Let's split these into separate issues ^^^

Since we can implement tags separately from the encouraging user stories while loading. Since validation is easy, lets define the more fun stuff and lump that into its own issue together too
