* RUNLEVEL_INIT does not exist (#75023)
This define shouldn't have been added (by me when I created runlevels)
people get it confused with RUNLEVEL_LOBBY and misuse it, like in this
verb subsystem I have no knowledge of.
- Removes RUNLEVEL_INIT.
- Fixed SSverb_manager not running during the lobby phase.
- Fixed Master.SetRunLevel having the potential to accept a scuffed
runlevel.
- Other standardizing cleanups to runlevels usage.
