Use an alternate logging library

The log4j exploit could have been prevented simply by not having these useless, unsecure systems in place in the first place, the entire job of the Minecraft logger is to simply write text to a file, why does it need to connect to servers and run arbitrary downloaded code???

My suggestion is that Mojang should use a more secure library that is simple and only does what Minecraft needs, preventing issues like this from happening in the future.
