_.each fails with objects with a length key

[jeffv]

var _ = require('underscore');

banana = {
length: 999
}

_.each(banana, function(val) {
console.log('Got Here'); //fails
})

If banana.length is a string, rather then an integer, it suddenly works. When I did I search I saw a long discussion on this subject back in march. Any head way made? This really surprised me when I came across it. There's nothing in the documentation saying this is a failure case when foreaching over an object.

I have a situation where I can't rename the key so I've had to ditch underscore temporarily.

See 5eaf71f, 942d6312, and 727db393 for the recent change that affected this. Still, an object with a numeric length value was treated as an array by _.each before then. That was decided long before those commits, and it's a decision I support.

This is a dup of #154 and #148 ... I've added a paragraph about it to the documentation -- see the above commit.
