Remove BOMs

I removed byte order marks (see http://en.wikipedia.org/wiki/Byte_order_mark).

The reason is that they end up in the markup of the web application running rack-mini-profiler. This caused an issue on my site where the footer (which is supposed to stick to the absolute bottom of the page) is followed by 10 pixels of empty space.
