Half implements #175
Things to do:
- Add ability to add tokens to the list.
- Persist the token tab selection (so it is an implicit preference)
- Check what's up with the token-tracker polling, it seems like it is not waiting the interval.
* Add mozilla plugin key to manifest
* Move all chrome references into platform-checking module
Addresses #453
* Add chrome global back to linter blacklist
* Add tests
- When unlocking, the first account is now selected by default and displayed as the main view.
- There is now a "CHANGE ACCT" button on the detail view to show the accounts list.
- Clicking an account from the accounts list now navigates to the detail view and selects that account.
- Config/Info screen "back" buttons now fire a new action, `GO_HOME`, which is configured to navigate to the accountDetail view, putting that logic in one place.
- When locking and unlocking again, the first account is always displayed, eventually we should persist the selection.
