Code spike for managed stripe accounts

[begedin]

What's in this PR?

This is a code spike for the switch to managed stripe accounts

What we have for now:

The process

1. Instead of a stripe connect button, we get a form to specify business information.
2. Submitting a form attempts to save a stripe-connect-account record to the server
3. Server, if stripity stripe uses the latest commit from Add Account.create beam-community/stripity-stripe#153, will create a connect account.

Related infrastructure, but not hooked into the process yet.

• The "bank account information" form is now also rendered and the action, with the parameters,
  is passed all the way to the controller, where it does nothing as of yet.
• All the tests have been fixed.
• A bunch of todos was added indicating how we should continue
• Email is bound from the current user
• I tried to make this as flat and self-contained as possible, so we can merge and split out individual tasks as much as we can.

We'll want to replace with http://engineering.teleborder.com/post/102323468281/ember-split-date-birth-date-selector-component

I might recommend not doing much at the controller level here and instead just write out the basic form fields per #853. Then we can slowly take that work and use it to break out into separate components in separate PRs, then actual integrated logic after that.

What do you think @begedin?

[begedin]

@joshsmith I got this as far as I could in the time I had. I tried to make it as easy to take over as possible. I believe it can be merged mostly as is and then the work that follows can be performed in smaller chunks.

[rileytaylor]

@begedin @joshsmith Merging and creating some issues for smaller chunks would be fantastic, I'd definitely be able to take a small chunk with the time I have right now.

Routing looks good, basic form setup checks out with the plan. I'm a fan of that pikaday component for date-picking.

[joshsmith]

Yeah as soon as I'm back from the dentist I will break it down.
