There's an api change that requires a thurd variable.

Ran into this issue when compiling and installing this on my fresh Ubuntu 13.04 install today. A note, the patch isn't quite complete. Even though the elantec and sentelic drivers may not be used, the calls to input_mt_init_slots need to updated for those as well, otherwise it won't build.

For other people reading this, I was able to get it to compile/install by adding an extra '0' argument to all calls to input_mt_init_slots so that it has a total of 3 arguments, as was indicated in the pull request.
