sys-con v0.6.1

* Fixed an issue that caused version 0.6.0 to always use 100% of CPU core 3
* The sysmodule will now detect both versions of Dualshock 4 controllers at the same time (thanks @p-sam again)
* * As such, the config option for it has been removed
* Changed how controller configs work:
* * Added separate options for both Left trigger deadzone and Right trigger deadzone.
* * Controller key mapping now supports multimapping, aka mapping multiple keys to the same button.
* * Additionally, you can also disable a key entirely, by writing KEY_* = NONE.
* * Previously, a line key_SYNC = LSTICK_CLICK would make the Sync/Capture button press the Left stick button, and make the Left stick button press the Capture button.
* * This has been changed, so that this would only modify the Sync/Capture button. The Left stick button would still press the left stick button.
* * The syntax has also been changed to KEY_CAPTURE = LSTICK_CLICK.
