My implementation of Bootswatch Switcher

Hi,

I started to implement something similar to your plugin. I merged yours with mine, here is what it became. You can merge it if you want. I don't really have time for it, so I'd be happy if you could take a look at it, and consider taking into account my solutions to the mentioned issues. Many thanks!
