Timeline Header Cleanup - Part 1: Move Keying Set + Autokeying Settings to Properties Region (NKEY)

Now all Keying Set and Auto Keyframing settings can be found the in NKEY
Properties Region (right-hand-side hidden tab/drawer).

This way, we have more room to display the full names of the settings,
without clogging up the timeline header.
