inequality operator wasn't working on a string

[razic]

In hyperarchy, I tried Question.where('state !=': 'bar')

and in the console I got this:

Uncaught TypeError: undefined is not a function relation.js:279
Monarch.Relations.Relation.Relation.predicateForKeyValue relation.js:279

Monarch.Relations.Relation.Relation.resolvePredicate relation.js:264

figured out why... there is no inequality != operator.

see https://github.com/nathansobo/monarch/blob/master/lib/monarch/expressions/predicate.coffee#L4-L10

was there a specific reason for leaving this one out?
