Bug 1245153 - Convert EventUtils.js to a module; r=automatedtester 

testing/marionette/sendkeys.js has been merged into the
new testing/marionette/event.js module, together with
testing/marionette/EventUtils.js.

There is a lot of functionality still left in this module that we can
probably remove, as it is not in use by Marionette.

--HG--
rename : testing/marionette/EventUtils.js => testing/marionette/event.js
extra : commitid : GvNeDeClc50
extra : rebase_source : 1390ceea688286318504c211ecfd34aa96725cdd
extra : histedit_source : f2fea53f3c7a5f49d1f0ef6f2bef4b98aa3566f2
