Merge branch 'release/2.0.2' into develop
added .try call for session variables

to check for nil
updated has_attached_file :path location

to :rails_root/public/assets because on standard
Capistrano deployments the public/assets directory
is symlinked to the app's shared directory, meaning
it will survive between deployments
bump version 2.0.3
Merge branch 'release/2.0.3'
