Subject: [PATCH] Update _src/jquery.iosslider.js

Added functionality to the removeSlide method.
Now a selected element can be passed instead of just an index.
The function will first look in the current slider for the selected slide and removes if possible.
If it does not find it, it will call the slider it belongs to and remove it.
Of course an index can also be passed to the function, in that case it operates using the vanilla functionality.
