Our support process is about to get more fully fledged so we’ll need
an index page to route people properly.
We reckon that users will also want to know what the support process is,
so let’s explain it on this page.
This commit:
- moves things around a bit on the request to go live page
- sticks a textbox in there
So when someone click the big green button, we will get a support ticket
that looks something like:
```
From Test User <test@user.gov.uk> on behalf of Test Service
(6ce466d0-fd6a-11e5-82f5-e0accb9d11a6)
---
We’ll send about 1000 text messages in the first month, and then 10,000
text messages per month after that. Usage of our service is about 50%
higher in March, at the end of the tax year.
```
