Using polled reading and don't allow actual LPR-ing in debug mode

* Source/AppController.m:
([AppController readChannel:]): Use libssh2_poll_channel_read() to check and see if there's more to read as it's much faster
([AppController uploadAndPrint:]): If BLU_DEBUG, do not LPR anything, but rather touch a file
