Add settings for security and privacy

[ShawnClake]

Add settings for encrypting:

• Comments
• Profile content

These settings should default to false for app speed and backwards compatability

Add user settings for privacy:

• Can others comment? Friend, Anyone, Myself
• Can other view profile? Friend, Anyone, Myself
• Can others find me in seach? Friend, Anyone, Myself
• More to come soon

For these settings, use an octal encoding. Each digit has a possible 8 states which corresponds to Friend, Anyone, Myself and leaves room for more options in the future. Then, this can be stored as an integer in the DB.
