v1.3.0

Added default sound channel count patch. This patch doesn't really do much because sound channels could already be changed with /console SoftwareSoundChannels 128, but I didn't want to let the hours I spent reversing the client to figure this out go to waste, so I'm including it anyway. I guess it can be useful for servers wanting to distribute custom clients with saner defaults, and also spares users from having to remember to run the command if they ever delete their Config.wtf.

Also added the large address aware patch, which sets a flag in the PE header allowing the game to use more than 2GB RAM, which may help with stability when using large render distances or on servers with custom content. This should be safe for 1.12.1, but if you experience strange crashes you may want to try disabling this.
