Enable color highlighting of Ruby, JavaScript, CoffeeScript and Sass source code within haml files in SublimeText

haml_embedded_languages.xml

<!-- 

	Add the code below into your 'Ruby Haml.tmLanguage' file.
	The file should be located in your sublime packages path.
	If you don't have one, take the 'Ruby.sublime-package' file
	from the 'Installed Packages' directory, change the file extension
	to zip and extract it into your 'Packages' directory.
	
	Edit: The previous version failed to match all the cases with a single begin/end pair.
	This version uses two rules instead of one. One for embedded language that starts without
	indent, and the other for indented blocks.
