luci2: fix various cross browser issues

	- add respond.js to fix page rendering in IE 8
	- fix datatype validation compiler in IE 8
	- fix RPC response type checking in IE 8
	- show/hide badges and labels since IE 8 does not support :empty CSS selector
	- fix wrong classes for radio and checkbox items, leading to broken rendering in Chrome
	- stop using deprecated arguments.callee
