Use awesomplete as autocomplete lib and remove jQuery - shaarli/Shaarli#148
* Add awesomplete dependancy (source + min + CSS) * Remove jQuery and jQuery-UI dependancy * Few CSS ajustements * Use tags complete list as RainTPL var (and display it as HTML) * Remove "disable jQuery" feature * Remove tag list web service
