Patchnotes:

- Added /launchpad command. This allows you to set a command for each launchpad that is executed whenever the player uses it.
- Added /launchpad permission. This allows you to set the permission that players need to use the launchpad or for the launchpad's command to be executed.

- You can now hover over a launchpad in /launchpad list to view more info about it.

- Changed the /launchpad command's description from "Create and remove launchpads." to "Manage launchpads.".

Enjoy!
