Set default initialization options

[RinkAttendant6]

In DataTables, there is an option to extend the $.fn.dataTable.defaults object so that the property values are used by default upon initialization.

Is there a similar functionality in Chosen? I've inspected jQuery.fn.chosen but there does not appear to be anything.

It would be nice to set the three placeholder strings (among other options, perhaps) in some sort of initialization/bootstrapper file instead of doing jQuery.extend in all the places that I instantiate Chosen.

I've once submitted a PR for this #1387, but the "discussion" apparently ended prematurely.
