Enable PERMISSIVE_HOLD to prevent accidental Cmd+Space

Using release order (PERMISSIVE_HOLD) instead of press order
(HOLD_ON_OTHER_KEY_PRESS) prevents accidental Command activation when
typing words ending in 'd' or 'k' followed by space. The mod-tap key
is treated as a tap if released before the following key.

Also adds D+K+Space combo for intentional Cmd+Space (Spotlight).
