First I jumped on replacing both jscs and jshint with eslint but
it might be premature decision. Although linting with eslint
is possible (like in there is wikimedia config for eslint)
it is still not clear should it
But in case the change happens we will be ready.
Apart from config stuff this changes few bits spotted by eslint:
improves some indentation, removes weird spaces, completes some
doc blocks, changes IIFE forms in tests. These changes do not
seem controversial.
