Major changes

I changed a little bit of everything in the project.
-- Comments can now be deleted (please don't test this)
-- Profile image now updates with whoever is logged in
-- Sidebar links now update the view to show the right leads
-- Added additional fields to individual leads
-- Fixed bug where lost leads were not displayed right
-- Removed active lead count
-- Added stub section for activation info
-- Replaced dummy email at top with generic text

Only two big things left to do now are:
-- Update lead information
-- Make new comments
