Removes jshint options from Gruntfile so that the .jshint file is used

Disables 'strict' checking in jshint
Turns of the eqeqeq jshint rule temporarily.

Douglas Crockford recommends ===/!== over !=/==. I have turned this off
as coffeescript transpiles 'null' check conditionals into the weak equality and
it requires further thought on a case by case basis on wether to use
v ==/!== null, v ==/!== undefined or v ==/!== null && ==/!== undefined
to be safe.
