"Jakefile" / "jakefile" should be recognized as having Javascript syntax

Jakefiles are Javascript-based makefiles.  They are becoming quite popular in the Javscript community (one of the main communities served by Sublime Text.)  They are used by the Cappucino project as well as the jshint npm integration.  Because they do not have a *.js" extension they are not being recognized as being Javascript in the automatic Syntax highlighting scheme.

It would be preferrable if both "Jakefile" and "jakefile" were added to the pattern for applying Javascript syntax highlighting.
