fix(ie10-): stop error from bad spacing in comments

Somehow there was a problem with this comment in IE 10 causing a
"SCRIPT1004: Expected ';'" error:

//Create a promise that will make our tracker active until it is
resolved.
//@return deferred - our deferred object that is being tracked

Closes #42.
