Intercom user_hash

Code for generating the user_hash value for Intercom's Identity verfication (Note: Identity verification was prevoiusly called 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, the final output needs to be in lowercase (the web version accepts both upper and lower case)

Local SSL websites on macOS Sierra

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on macOS Sierra, but they have been known to work in El Capitan, Yosemite, Mavericks, and Mountain Lion.

	* Fix for vw, vh, vmin, vmax on iOS 7.
	* http://caniuse.com/#feat=viewport-units
	*
	* This fix works by replacing viewport units with px values on known screen sizes.
	*
	* iPhone 6 and 6 Plus cannot run iOS 7, so are not targeted by this fix.
	* Target devices running iOS 8+ will incidentally execute the media query,
	* but this will still produce the expected result; so this is not a problem.
