1. trying splash screen

2. Changed notation in help from "Web" to "Android"

3. changed to quit on suspend to avoid problem
where when the app is re-entered, it pushes a new copy of it onto
the webview stack and the one underneath has the focus; and you
have to hit back multiple times to get out of that, they stack up.
Making it quit on suspend will add a few second's lag when coming
back in, but that's better than having it hung up once back in.
PhoneGap bug, this does not happen when using as a web page.
