Add potential rule for IIFE case

[markelog]

See eslint/eslint#6613

That's what holds up adding indent rule to this config

[markelog]

Tried it, failed, first of all there is lots of inconsitancies we have in the core and indent autofix feature is not ideal and second of all we need eslint/eslint#6690 to be fixed

[platinumazure]

Update for anyone following this thread: indent auto-fix will be improved with today's eslint@3.6.0 release (it can fix spaces to tabs and vice versa, and even fix mixed spaces/tabs to the proper indentation).

However, we still need eslint/eslint#6690 to really be able to use indent in jQuery projects.
