Fix documentation

[Former user]

On the page for responsive calendar, you have documentation that is incorrect:

$('#slider').responsiveCalendar('prev')

is one example. You also have a copy/paste from the slider in the calendar:

"The slider have entire markup exposed to you so you can easily edit it by for example adding your own classes. Note that you don't need any of the classes that you can see in the example however [data-group] properties are obligatory. You can initialize the plugin and set options directly from markup using data interface. For example, you can set captions animation properties by setting data-animate, data-delay or data-length. By data-jump attribute you can set prev/next buttons and by using data-jump-to pages indicators can by easily setup. In this example we initialized the plugin by using data-spy="responsive-slider"."
