Idling consumes ~5% CPU usage. #146

On linux (and maybe other systems?) Libra consumes ~5% cpu usage when idling. There is no reason for this CPU usage, so its origin should be tracked down.

Can not repro on Windows.

Tested in both locally compiled version, and beta 1.3.

Libra sits a 0.03% CPU at idle, both before file is loaded, and while file is paused.

This is caused by the Timer peripheral's parent timer. As a result of this CPU consumption, the Timer will be disabled during Stepping mode.
