Title: bug 823385 - Show developer provided description of a permission inside the permission prompt. r=vingtetun.

I had added permission description to geoloc's manifest.webapp to test it.
Altought permission description is mandatory in manifest it's still not present in it, so if you want to test it with another app, don't forget to add the description to its manifest.
