Profile Page

## Implementations
- Reverted to a more simple profile page
- Implemented styles
- Feature spec for profile page (oauth stub currently hardcoded to @mecampbellsoup's venmo acct attributes)

## Future Considerations
- Need to make Venmo auth more dynamic (as in, allow any user factory to be dynamically logged in to Venmo instead of just hardcoding @mecampbellsoup's venmo acct attributes)
- Add in more Venmo oauth attributes (profile picture, venmo url, venmo username)
- Add in functionality for cancelling Venmo account, edit Venmo account attributes and updating that attribute in Wager)
F*ck it, let's merge this. That way if we want to make this stuff editable in the future we don't have to change back from `show` to `edit`.
