*
* This simple slideshow plugin will provide your effect gallery with
* some simple features:
*
* - auto slideshow with repeat and a lot of options
* - callback for slide changing (gotoSlide) and slide Clicks (onSlideClick)
* - different option variables to configure
* - change of slide through clicking numbers, next, prev etc and mouse
* movement over the slides
* - text over images possible
* - random start slide via { start: 'rnd' }
* - start/stop slideshow and read playing status
*
