Tweaked BhWaxDemo to work for iOS6

Hi Andy, I fixed the main demo file for Youtube/iOS6 incompatibility & tweaked the html string using Lua multi-line strings for better readability within HTML/Ja-line strings for better readability within HTML/JavaScript heavy content.

For some reason, I can't get the BhWaxAutoComplete demo to work. Xcode keeps complaining:

*callFile* stack NOT ok begin:1 end:4 delta:-1
main.lua:97: attempt to index global 'BhWaxAutoComplete' (a nil value)
stack traceback:
	main.lua:97: in main chunk

Any ideas? I pulled down all the repos fresh from today.

Best,
