Fix $.globalMessenger().hookBackboneAjax(). Previously it was not accepting options & potentially clobbering options that did exist.
Only clone options when necessary (perf)
Remove unnecessary check for options.messenger
Rewrite hookBackboneAjax based on comments, now overrides Backbone.ajax if it exists
Updated package.json to 1.1.0 and built
Simplify the hookBackboneAjax option cloning syntax a bit, fix typo in
Backbone version comments, Add _withoutMessenger object to keep a
reference of what Backbone.ajax was before our meddling.
