Default CSS stylesheet with no styling

[drawcard]

Hi,

Just an idea, it would be great if jPushMenu had a default CSS style that didn't have any blue backgrounds / border / bullets etc. As I use this script for client sites, it's a hassle to override all of those styles, particularly if we are using Bower and there's no opportunity to directly edit jPushMenu's CSS directly. Perhaps instead the blue styles could be seperated into another CSS file that can be toggled on or off based on user preference.

The file I refer to is: https://github.com/takien/jPushMenu/blob/master/css/jPushMenu.css
