Disable the Reload command

The reload command is fundamentally broken. It is known to cause several issues such as crashes, memory leaks and in some plugins  unexpected behavior or disabling. This is known by most large server owners but some smaller less experienced owners don't understand why these weird occurrences occur, and don't connect them back to reloading.

As a result, I propose disabling the command until it actually functions properly, in a similar way to how we disabled the timings command since there was an alternative that actually worked. The alternative case here being doing an individual plugin reload or restarting the server.
