Peter Hutterer d6e1f93812 plugins: update plugins for the current API
A few changes to the Lua API didn't get reflected in the example
plugins, let's update them.

Also included here is naming of all arguments, instead of _ use the
argument name even where unused. These are examples so being expressive
is more important than making any lua static checkers happy.

-- This plugin implements a very simple version of disable-while-typing.
-- It monitors all keyboard devices and if any of them send an event,
-- any touchpad device is disabled for 2 seconds.
-- And "disabled" means any event from that touchpad is simply
-- discarded.
