Migrate to add featured column to users.

I decided to let users own this column, rather than profile, since a
user will only have one profile.
Update routes, and remove home/index view.
Update home#index to sample from featured users.
Merge branch 'add-devise-recoverable-6' into setup-featured-profile-34
Change debug level to :debug on staging.
Add feature attribute to User's strong params.
Merge branch 'master' into setup-featured-profile-34
Add Reset Password modal to homepage.
Merge pull request #35 from vitaliyg/setup-featured-profile-34

Setup featured profile 34
