Before, you could "Enable swapping" without specifying which type
of protocol to enable. Now, the two switches are clearly delimited
between bluetooth and wifi.
The Toolbar is the new thing from Google which acts as an ActionBar.
It is not a special view like the action bar is, it is
implemented and added to your layout the same as any view.
The InnerView classes of the swap workflow have the choice of what
colour to make the toolbar, so that they can distinguish themselves
as per the mockups (some deep blue, others bright blue).
Added icons for close, but they don't do anything yet.
Minor tweaks to layout so that it looks more like the latest mockups.
All the code from the activity and the fragments has been successfully
ported to the SwapWorkflowActivity + Views. Thus, the code is no longer
useful, as it was only kept over the previous WIP commits so that it
can be referred to to help re-implement fragments with views.
As per the select apps list, there is quite a bit of business logic
in this class, which is now spread between the activity and the view.
The activity needs to handle some stuff, because the zxing library
routes intents to either an activity or a fragment.
