refactor: use ES6 fat arrows in application code (#522)

Browse Source 
ES6 fat arrows provide reasonable `this` behaviour, which protects us
from some subtle accidental bugs, and erradicates `const self = this`
from the codebase.

Far arrows were not applied in Mocha code and AngularJS
controllers/services constructors since these frameworks rely on
`.bind()` on those functions.
