Make !reload command always available, add !finishevent

The reload command was previously implemented in Lua, but this
is a little dangerous as it could itself have an error and is
unable to work in the first place. I moved this to Rust to
ensure it's always available. I left the reload_scripts() API
in Lua as someone could still find that useful!

Additionally, I added a !finishevent debug command to forcefully
end the current event you're in. This can be useful if your script
is incomplete or has an error, as your client gets stuck very
easily.

 * `!invis: Toggles the hidden GM invisibility mode on or off for your character.`
 * `!unlockaetheryte <on/off> <id>`: Unlock an aetheryte. For the first parameter, the literal words are required.
 * `!teri <id>`: Changes to the specified territory.
+* `!finishevent`: Forcefully finishes the current event, useful if the script has an error and you're stuck talking to something.
