fixes #151 Updated ICanHaz.js

The current version of ICanHaz includes a version of Mustache.js with wrong escaping: https://github.com/HenrikJoreteg/ICanHaz.js/blob/v0.9/ICanHaz.js#L252-L264  
By updating the version of ICanHaz.js backslashes will appear as expected: https://github.com/HenrikJoreteg/ICanHaz.js/blob/master/ICanHaz.js#L43-L49

Another approach to consider is to use [ICanHaz-no-mustache.min.js](https://github.com/HenrikJoreteg/ICanHaz.js/blob/master/ICanHaz-no-mustache.min.js) and include the latest and greatest version Mustache. But for updating the library will suffice.
