Combat update for Bedrock Edition (and ways to upgrade it from Java)

As most people know, Java Edition enjoys a more complicated combat experience than Bedrock (e.g. weapon cooldowns, sweep attack on the sword, heightened damage on the axe, the ability to put anything in your offhand, etc.), which is why we need to have Java combat added to Bedrock. 

However, there is a problem. In Java edition, there are people who hate the combat update so much, they play on an ancient version of Minecraft just to avoid the weapon cooldowns. This is why I suggest making it so that the new combat is optional, and can be toggled on/off in the world settings.

It is simply too easy to do PVP with an auto clicker on Bedrock. Let's give those spammers a hard time!
