Title:  	Fixed problem with void ac-define-source. Unicode symbol on ac.

We definetly use differend indentation settings. So this diff is huge, but the only important part is:
```
(defvar ac-source-js2
'((candidates . ac-js2-ac-candidates)
(document . ac-js2-ac-document)
(prefix . ac-js2-ac-prefix)
(symbol . "")
(requires . -1)))

(defun ac-js2-setup-auto-complete-mode ()
"Setup ac-js2 to be SED with auto-complete-mode."
(add-to-list 'ac-sources 'ac-source-js2)
(auto-complete-mode))
```
This solved problem with ac-define-source function void on my setup.
