Timo Tijhof 1a2daca06a Kranitor: Make JSHint pass
eqeqeq:
* Change loose comparisons to strict comparisons where
  it seems safe to use a strict comparision instead.
  Mostly comparisons to strings or objects, and comparisons to
  numbers where the other value is known to be a number, too.
  E.g. foo == 'string', bar == node, indexOf() != -1.
* Add eqeqeq:false to files where there are non-obvious usages
  left.

onevar, quotmark:
* Disabled in files with lots of style violations.

unused:
* Remove unused variables that have no side-effects in their
  assigned expression.

Coding style cleanups on affected lines where trivial.
