Feature/style login pages

Hey there, this PR implements tracker story 67127028, [Style Account screens (Log In, etc.)](https://www.pivotaltracker.com/n/projects/890876/stories/67127028)

See the related [IOS PR](https://github.com/jmoody/wetap-ios/pull/69)
Seems like this is a popular bug with ios / embedded safari. 

There are listed work-arounds:

But the behavior isn't what I want. Here's what I see;

```
Given I've implemented the ontouchstart hacks
When I press the twitter droplet
Then I'm expecting to see the twitter droplet display the active style for a bit
And shortly thereafter the twitter login page will load
But Instead I see the keyboard activated
And the keyboard shortly dismisses itself
And I see the embedded browser rendered the "Resend Confirmation Instructions" page, as if I'd clicked the "Resend Confirmation" link
```

This seems like a hairy bug, and I'm inclined to punt on it.
