Verdun test group for future builds

Our character system was pretty heavy to render and caused lagspikes whenever characters spawned. Especially on lower systems this was more noticeable. We have now worked on improving this to improve general FPS and remove lagspikes from the game.

This has been quite an overhaul and can introduce bugs, therefore we really need your help in testing this. Currently we have this build live on the opentesting branch.

You can switch to the opentesting branch with the following steps:
1. Right click on Verdun in Steam library
2. Properties
3. Go to Betas tab
4. In the dropdown select 'Opentesting'
5. The game will now have to download the new version

With this version you can still play with other users but you might experience some bugs. If you do, please report this on the Verdun forum so we can roll this out quickly for everyone. Also we would like to know if you experience improvement from this overhaul

KNOWN ISSUES:
1. Zombie hands when spectating
2. Floating ragdolls
