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!

Ok, I came up with an example.

Programming is like doing a massive sudoku. But you’re not just doing your own square; you have to line up the edges with squares that you’ve already done, or squares other people in your team are working on.

And it’s not just squares that you’ve done — you have to anticipate the sudokus you’ll be doing days, weeks or months from now, and leave easy numbers at the edges so it isn’t impossible to do those squares.

And that’s why some programmers are so engrossed in it, and get all worked up, because they’re like “You left a 5 in the middle of the square, what kind of asshole does that, now I’m gonna have to line all my squares up with that.”

And then someone points out a bug, and you have to trace it back to the square it came from, and then redo that square without screwing up all the other ones.
