fixed most of the errors associated with validations. BUT if a user tries to edit their profile and enters in a PW that is too short they will get an error: @teams=nil
fixed the users show page so it only shows the users feeds. i also editted the DB to be able to test this
adjusted navbar
mike is having issues with getting nokogiri to work. but this should be the fullest version to date with nokogiri working and loading feeds to a users page
