sproutcore-touch.js is generated when using the bpm package

[lukemelia]

TransformJS' package.json specifies sproutcore-touch.js as an output file. I think this is for the included demo.

As a result, though, if you use the TransformJS bpm package in another project, you will end up with sproutcore-touch.js being output to your assets directory, even if your project doesn't use it.
