Issue with MVC 5.2

Hey Andrew,

Our project is using Postal 1.0.0.0 for MVC5 and since updating to System.Web.Mvc 5.2, it all stopped working. This is in my assembly binding Fusion log:

```
=== Pre-bind state information ===
LOG: DisplayName = System.Web.Mvc, Version=5.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35

```

I have my binding redirects setup correctly under my web.config:

```

```

No other components have this issue except for Postal. I noticed the dependency for Postal for MVC5 is >= 5.1.2, so 5.2 should be working, but Postal is somehow requiring 5.1.x.x specifically.

Any ideas?
