Updated ClientProxy to match version 1.5.2 (Dev jars are here)

[Gamingb3ast]

Matches the decompiled class file found in the binary file llibrary-1.5.2-1.7.10.jar

Created to allow devs to get a dev jar for when they wish to use this repository.

(Hey Gegy, can you please upload dev jars to curse forge?)

[Gamingb3ast]

Hello, I figured out how to do it myself, so this isn't really necessary unless ya'll want it anyways, gonna leave the dev jars here in case anyone wants them, if the devs could upload them to curseforge that would also be great just so no one has to dig super deep for them.

Here are the files https://github.com/Gamingb3ast/LLibrary/releases/tag/Release
