Add argument to control whether NamespaceResolver attempts to pair mangled constructors

[ZombieProtectionAgency]

I ran into a few issues with Resurrect-JS while messing with one of my scripts. Enabling variable mangle in uglify mangled constructor names and broke NamespaceResolver. I was going to make my own or manually wrap the internal resolver but I came up with this change to automatically resolve my objects even if I update them later. I think it could be a really useful feature.

I created a couple performance tests here. The (un-uglified) source object I used is below

var TestNamespace = {
    parent: (function() {
        function parent(name) {
            this.children = [];
            this.name = name;
        }

        parent.prototype.addChild = function(childToAdd) {
            this.children.push(childToAdd);
        }

        return parent;
    }()),
    child: (function() {
        function child(parent) {
            this.parent = parent;
        }

        child.prototype.check = function() {
            console.log('Child object check.');
        }

        return child;
    }())
};
