- Updated to 1.20.1
- Fixed a typo that appears saying "the amount of type you spend in the air is now set to xseconds" (with no space between x (your number of seconds you've set) and "seconds".) There is now a space between x and seconds.

- Added a new command: /changeairtime (as requested by @Emegnowski)
How to use it: /changeairtime <seconds>
What it does: changes the amount of time you spend in the air when gravity is flipped upwards (while not changing the amount of time spent on the ground/the main time).
Please do remember that when you use this command, you pass in the amount of seconds as an argument, NOT minutes.

Added description for commands.

- OPs will now get a warning to set "allow-flight" to "true" whenever they join.
- Fixed bug where it would say "Gravity flip is now turned on" when it was already turned on. Now it will say "Gravity flip is already turned on" instead.

This update includes new functionality for the /enable command.
- Players can now set the time between each swap to whatever they want.
Example: /enablegf 5
And then the gravity flip would happen every 5 minutes.

This update only contains bug fixes.
- Fixed bug where it would say "Gravity Flip has been turned off!" instead of "Gravity Flip is already turned off!" when gravity flip was already turned off.
- Fixed bug where if you left the server and turned it off while the gravity was flipped upwards then turn it back on and rejoin, the gravity would still be flipped upwards with absolutely no timer ticking down to 0 and the player would be stuck in mid-air until the /disablegf command was run. This won't happen anymore.

This update includes a new command:
- /showfliptime
This command does not take any arguments, it simply shows you how much time is left until the next gravity flip.
Everyone (including people without op) is allowed to use this command.
