[Plugin: W3 Total Cache] Change javascript mime type

Hi, I noticed that w3 total cache uses “application/x-javascript” as mime type for the javascript files after minification.

I would like to propose a change to the more widely used type “application/javascript” (with out the “x-“).

This type is used in html5 boilerplate, apache, google cdn and more.
