this makes it so the create profile wizard uses the generic wizard js
(mozilla/xpfe/global/resources/content/wizard*, mozilla/xpfe/global/resources/content/widgetStateManager.js)

I made changes so that:
1) exit quits the app, and doesn't start up app with the last current profile
2) fix a spelling error (personalisation -> personalization), this is en-US, not en-UK
3) fix it so start actually starts the selected profile.
4) -SelectProfile launches this new dialog
5) if the user starts with no command line, and they have more than one profile, they get -SelectProfile, and not -installer.
