Add support for the getAutonym callback

A getAutonym function can be passed as an option
when initializing ime, to give a possibility to load
autonyms of languages that don't have input methods
defined.

This is a step to resolving the following downstream bug:
https://bugzilla.wikimedia.org/show_bug.cgi?id=51025
Do not inlcude rangy in the jquery.ime single file version
Merge branch 'master' of github.com:wikimedia/jquery.ime
Merge branch 'master' into bug-51025
Cleaner getAutonym()
Revert "Pass rangy as a parameter to the closure"

This reverts commit 67a0e53d4b159b276c8eb4201a440a604a6049ba.

Loading rangy in such a way doesn't work with the way
jquery.ime is loaded in the MediaWiki ULS extension.
The issue is reported as
