Bug 1069915 - Privacy Panel

This is a new pull regrets for the Privacy Panel. I am very sorry to open another pull request instead of reopening the old one, but before I thought twice I have deleted my mold branch and had to reopen everything from the beginning. 
`Connectivity` was definitely removed 17 hours ago, so there might be some problems there when rebasing onto master. Please check https://github.com/mozilla-b2g/gaia/commit/d5562731ae2c1eb05a887026301d1b20a16625eb#diff-5e40f6309b04c2f2bb5303478a0cd553L24 and make sure this Connectivity is removed.
