core: fade out improvements (#194)

* core: allow fade out for grace unlock

* core: disable input once fade out started

* core: render when fade out started

* core: allow fade out for other compositors

Works fine in sway altough it fades to a black screen not to the desktop.
Still looks kinda good.

* Revert "core: allow fade out for other compositors"

This reverts commit adfeb543ad.

* misc: rename lock and unlock functions
