Although I expect this to be faster (linear time), this produces
incorrect results for certain arrays due to the implicit toString().
Arrays of DOM elements might not be properly uniq-ed, for example.
The same is true for the following array (which uniq() handles
properly):
var a = [true, "true"];
console.log( a.uniq() );
// [true, "true"]
console.log( uniqueArray(a) );
// [true]
