filelist fix for FFOS 1.2
fix for the "pick activity empty result" bug at picking a ringtone

I tried to pick a new ringtone over Prospector and always got "pick activity empty result" from the settings app.

With this fix it works now. Main problem was that the settings app requires a Object with a blob and an name property and not just a blob.

I tested it with ringtone and wallpaper picking, both worked quite well.

resolution fix for 1.3

on FF OS 1.3 the app had a to hight resolution and the whole UI was to small. With the viewport tag, this will be fixed.
Normally the viewport tag should always be used. I don't know why it worked without it so far...
