toggle_touchpad.sh

Added a small program to toggle the touchpad status by using xinput on the
"SynPS/2 Synaptics TouchPad" device's "Device Enabled" property.

For some reason, after a hibernate/resume, the touchpad toggle button on my
Lenovo stopped working. But the F6 key still works (i.e. Fn+F6) so I mapped F6
to this toggle function in my window manager (fvwm2) so I could continue to
have this functionality.
