Make it so we can reload a single event/command

[falcao-g]

Feature description

Right now we can either reload all commands, or all events, but normally we only want to reload a single command/event

How to implement?

The /tools command only calls the loadEvents and loadCommands function, and these two functions just rewrite all commands and events, so this causes them to be reloaded, if we wrote new functions that only reloaded a single command/event we could call those
