Intercom user_hash

• Code for generating the user_hash value for Intercom's Secure mode
• Based on http://www.jokecamp.com/blog/examples-of-creating-base64-hashes-using-hmac-sha256-in-different-languages/#ruby
• When creating this for mobile secure mode, the final output needs to be in lowercase (the web version accepts both upper and lower case)

Remember that your secret key should never be exposed to the public

• So Javascript code below should only be used for testing unless modified and used to run on a server
