Replaced pure CSS with Less.js CSS-generating code for improved maintainability and ease of future changes to overall CSS.
Removed old CSS stylesheet
Removed 5th state: Finished.
Now showing progressIndicators for states that aren't finished but aren't the current state, but without a special background color.
Fixed the delivery details section, where it was still reliant on old Sessions that were removed in past commits.
Fixed: Using too much sessions for one thing. Also, client-side code transferred from lib(server) to hooks(client) for cleanliness
Merge with branch lessJs
