This is my first ever bootstrap commit. I've added a option 'stayOnHover' (default = false) which will make the popover stay when mouse hovers over it and automatically hide as soon as mouse moves out of it. This is a very useful feature and many people need it. I've also added an option 'stayTargetClass' which will add a user-provided class to the class names list of popover (so that user can select and manipulate the popover using that unique class). If not given, it internally generates a random class name.
