Bug 1023950 - Implement real state handling for mozApps and apply visual...

 - gaia-confirm now has a JS + DOM Event API (I updated the example)
 - mozApp states are now handled entirely by gaia-grid which means l10n changes (moved to shared) many additional tests and some nicer code (which depends on bug 1027458)
- visuals for app states
Can you open a bug, makes it block the vertical-homescreen, add the bug number here, so I can eventually found someone to fix it tomorrow :)

All those are so long that you may even fix that directly ;)
