These collections should always be operating with the same model
instances, so let the inbox reset it self from the same in-memory
cache of conversation models used by the conversation windows.
If all the application windows are closed (and not merely hidden), the
background page will go inactive and there's nothing we can do to stop
it. However, we can ask chrome to trigger an alarm once per minute,
which will spin up the background page and check for new messages.
This will effectively keep us alive as long as chrome has open windows
or is running in the background, subject to chrome settings'
Advanced -> System -> Continue running background apps
As a chrome packaged app, we have to keep at least one window open in
order to maintain our websocket connection in the background page.
This change replaces the system window frame with custom buttons in the
inbox header, such that the 'close' button merely hides the window
rather than unloading it.

FREEBIE
In a multi device world, it's possible to receive a receipt for a sync
message before the sync message actually arrives. In this case we need
to keep the receipt around and the process it when the message shows up.
My current version of chromium inexplicably exposes a crippled version
of chrome.browserAction even though we are now a packaged app and should
not have that functionality exposed to us anymore. This results in some
errors to the tune of "property 'foo' of undefined".
It also doesn't support the innerBounds property for window creation,
only the older (deprecated) bounds property.
Also make it accessible by providing a mode argument to the install
function. Previously developers could just edit the url but we no longer
have the address bar as an app window, so now they must close the
default installer and run the following from the background page
console: `extension.install('standalone')`.
In the production build, this should result in an error since it is not
supported / the register page is not included there.
Appify tabs, windows, browserAction
Port the extension.windows.focus function to new window api and
generalize its error handling in the case where the requested window
does not exist. An error will be passed to the callback.
Port extension.browserAction and rename it to the more generic
extension.onLaunched.
Use of the id option when opening a window ensures that attempting to
open a duplicate window merely focuses the existing window.
Finally, after registration, close the options window and open the
inbox.
Port extension.remove
