Create UI elements for each property in account model.

- Add UILabel properties and setup in createUIElements method.
Wrap the AccountView in a UIScrollView.

With the amount of properties that will be
in the view (and the possibility to add more
over time), a UIScrollView will allow users the
ability to see all the content.

- Add a UIScrollView and initialize it with frame properties.
- Set the contentSize to static values (for now).
- Update references to adding current views to the scrollView.
Set default text to UILabel values if property is not set.

- Add some TODOs that need to be researched.
Show user a message when no Twitter Accounts are configured.

- Add new method to AccountManager to return number of accounts.
- Change AccountList implementation to build UITableView when needed.
- If no Twitter Accounts are present, show user a message instead of TV.
- Remove unneeded comments.
- Move methods around to the proper pragma mark definition sections.#
Use TwitterAccountManager to store AccountDetails.

As part of refactoring, this commit is starting to consolidate
some of the management of the Twitter Account details into a
single class. Ultimately, PPSTwitterAccountManager should be the
single point to get all data needed. The other classes will be used
as helpers to retrieve the data.

- Move accountsWithDetails dictionary to PPSTwitterAccountManager.
- Update references to retrieve accounts with details.
- Setup the AccountListTableViewCell to pull from TwitterAccountDtls.
Add helper method to set label values in AccountView.

The BOOL and NSUInteger values are being wrapped in a NSNumber
object so the helper method can use id and then make the correct
descision on how to format the value. BOOL and NSUInteger are
primitive types and cannot be passed via id (expects an object
pointer to a class).

- Create new method, returnStringForValue, to handle setting text.
- Set all value labels in setAccountDetailsValues.
- Change BOOL and NSUInteger to NSNumbers (including references).
