Refactoring StackMob Titanium module to be standalone

I refactored the Titanium changes so that they can be standalone in their own file.  This will make it more durable in that as the StackMob JS SDK evolves to 0.9.x, 1.x etc, you won't need to reapply your changes every time.

**Usage**

```
<script type="text/javascript">
/* I need to figure out a better way to handle window in the StackMob JS SDK, so for now, maybe just put it out here :) */
var window = {
  location: 'cnn.com',

};

</script>
<script type="text/javascript" src=".../stackmob.js"></script> <!-- This is the stock StackMob JS SDK.-->
<script type="text/javascript" src=".../stackmob-titanium.js"></script><!-- These include modifications via _.extend() to the StackMob JS SDK -->
```
