Add seat <seat> idle_{inhibit,wake} <sources...>

This adds seat configuration options which can be used to configure what
events affect the idle behavior of sway.

An example use-case is mobile devices: you would remove touch from the
list of idle_wake events. This allows the phone to stay on while you're
actively using it, but doesn't wake from idle on touch events while it's
sleeping in your pocket.
