Add information for juggernaut

[marcoSchr]

This Pull request will add information about the Juggernaut role. This will solve #95

[whichtwix]

its sort of meant to be a secret role, hence no info on here

[marcoSchr]

What is the advantage of keeping the role "secret"?

I only see a disadvantage, as every time someone gets the role, they ask, what it does exactly. The ingame description is not informative enough and one can not point new players to the readme for the role, as it is not documented there.

its meant as a surprise for new players, and ig 1 reason it can be is lowering kill cd doesnt need explanation as much unlike any other role and it can still be noticeable

Settings and an on/off switch for Hidden Roles and information will be available next update.
