Changes:
- Moved alias mapping from Constants.cs to Stages.cs.
- Added `odyssey` as an alias.
- Hardcoded all known stage values.
- Verfify that the stage input is either a alias or a known stage name.
- Added an option to append `!` to a stage name to force sending even if the stage is not known (e.g. for custom kingdoms).
Before it only checked that it was a known alias or that it contained `Stage` or `Zone`.
That made it impossible to send players to`MoonWorldShopRoom` and `MoonWorldSphinxRoom`.
And a typo would have resulted in a game crash.
