Improved swipe gestures plugin for jQuery

What was changed (compared to the original v0.1.2):

• Don’t modify the default settings internally.
• Merge the options recursively (deep copy) so that the custom threshold values actually get used.
• Allow overriding the options globally through $.fn.swipe.options.
• Use namespaced jQuery events (using the swipe namespace) instead of DOM2 addEventListener to prevent errors in old IEs.
• Simplified and optimized code.
• Changed swipeLeft and swipeRight functions to be called within the context of the bound element. Thanks, @kswedberg!
