task, projects, comments, memberships, only accessible to logged in users
tightening up accessibility, users can only access thing they are associated with (still some loose ends)
members cannot manage memberships
users can only edit themselves
users can only edit their own profile
added before destroy to membership and message for last members
users can no longer see other users emails
users can now see emails of others who share a project
added dropdown to header and link to users to header
made it so only project owners can edit projects
