[Hotfix] Alpha 13b

Game saves backward compatible: yes
Content packs backward compatible: yes

Small update for a major bug fix, also includes a new discreet feature.

New feature

Folder mode content pack: This feature is a little bit hidden, in the edtior, save your pack with "File > save as" and choose a newly created folder, the pack will be saved inside without beeing zipped. This is useful for easy management of packs with a version control system like git. In folder mode, you directly manage your resources with your OS file explorer. In the main project's code (https://github.com/JoannickGardize/Pixurvival), the Vanilla content pack is now saved this way. In this way, and thanks to the humanly readable content pack code (in the file contentPack.yml), we will see changes in the git commits differences.

Bug fix

• Fixed a major bug that makes impossible to start a multiplayer game with a GameMode using the Role feature, making pig revenge of vanilla content pack unplayable. Pig revenge is great again!
• Fixed some translations in the editor
