Updated rspec-expectations gem from 2.14.1 to 2.14.2. Updated mime-types gem from 1.23 to 1.24
Removed all Relation.all calls.

This removes a deprecation warning from the logs. It seems this method is deprecated and will eventually be removed.
Removed "uniq: true" from model associations. Instead use a "-> {uniq}" scope in each relevant association.

For a very good explanation on how association scopes work (rails 4 new feature) see:

Removed hardcoded paths to image assets. Use asset_path helpers instead.

This future-proofs against rails fingerprinting asset filenames.
