* This makes `geyser reload` work the same across all platforms. For example, it ensures that we reload the config to the greatest extent possible (with the exception of compression/injection settings). Additionally, this clears up issues where Extensions were previously disabled during reloading - instead, the new Pre and Post reload events allow extensions to reload whatever necessary on their own.
* Fix duplicate permission registration
* Register /<extensionid> help (and aliased ?) commands under the "geyser.command.exthelp.id" permission
* Fix: Show correct header for /geyser help vs /<extensionid> help
