Add LookML as Syntax formatting option

Hi!  I do lots of development in a platform called LookML, used by the BI software called Looker.  It would be great if I could view the syntax highlighting in sublime without having to import files into Looker to see their syntax highlighting.  

If you are interested in this, you can reach out to our support@looker.com address, or me directly at andy@looker.com.  Thanks!  I love sublime and would love it even more with this feature, but still will use it either way!
