Double Take Script Loader

This has been moved to an official Git repository

@klamping, thanks for the feedback. I'll look into the timeout concept a little. But I believe that the browser waits for each script to load/fail before moving on to parsing the rest of the document (hence the "best practice" of including scripts at the bottom of your page right before the tag).

Note to self Figure out a way to add an option for libraries that attach themselves to the namespace of other global variables (like jQuery plugins or AngularJS modules).
