UI adjustments from user interviews

[Derekf5]

• [x] 1.Technical stats in the UI are likely to hurt more than help understanding, we should remove them.
• [x] 2. Add a more in-depth explanation of the Lantern network on the main page below the fold to aid user comprehension.
• [x] 3. To increase trust, provide some high-level points about data collection and privacy and link to a privacy policy.
• [x] 4. Add a headline lantern.network.io that communicates who is benefiting from turning this on.
• [x] 5. Remove the external links (to lantern.io, and our donate page) from the control panel area; users often clicked them and got confused before activating the toggle.
