Cooldown

With this command, it will be possible to impose a fixed recharge on any item. Or choose the "radius" option so that the recharge can be, for example, from 5 seconds to 10. It is also possible to change the recharge of things that already have it with this command, for example, to lower the recharge rate to 20 seconds for the horn, and to increase the Ender pearl to 2 seconds.
