Title: #23 - Fix when using sketch.js on mobile devices

Fix when using sketch.js on mobile devices, due to the touchend/touchcancel events never get fired.

I did this on my end, directly on javascript and it works. I believe these changes are the coffeescript equivalent.
I did not test nor compile the project though.

This also fixes issue #19.
