v.2.2.0 - back-to-the-css for themes

Related issues #54 #60 #162

noty is not forcing you to include theme.js now. If your theme-name doesn't have a equal theme.js; noty will use your theme-name as a css className.

Check this demo page: demo/themeCss.html

Also; there is no backward compability issue about that. Everything works fine. But I deleted BC option overriding control in noty helper function. So you must use noty with 2.0.x options. (1.0.x options support dropped now)

Structure will be like this;
<li class="yourCustomThemeName noty_container_type_alert">
	<div class="noty_bar noty_type_alert">
		<div class="noty_message">
			<span class="noty_text">noty text/html</span>
			<div class="noty_close"></div>
		</div>
	</div>
</li>
