separate layouts for edit and view
Edit fragment fleshed out
Fleshed out view fragment
Asking the parent activity to switch the fragments

Using ARG_ITEM_ID for intent extras as well

Taking a queue from the app template's code
TextView, not EditText, in view fragment
Don't test encryption on each resume
reformatting
single top (Nick Butcher's tip)
Updating fragments in onResume instead of onStart

Nick Butcher's tip
Extraced base fragment class, save/load moved to IO
Saving immediately on every change
Edit fragment forgot to call updateRootView
Using the same fragment switching code

Exposed as a static method in PasswordEntryDetailFragmentBase. Not the cleanest

Authorization activity resets in onResume, can't paste from authenticator
Can now change the password
Notification to copy password to clipboard WIP
notification won't show without an icon
forgot to call super.onCreate
