Add a way to test/try blob in ghost vr

[Kotlol]

Almost all antags can be tried out and tested in murderbox but not blob thus resulting in many inexperienced  blob players. I suggest adding a blob button that transfers you in a empty room (like blob tutorial) for you to test/get accustomed to blob and its binds. Would be good If it had a training dummy like murderbox to see damage numbers

Currently you trying it out just before starting the round in my opinion isn't viable since most times your blob bros might deploy early and if you are new either end up alone as last blob or deploying getting found early and dying due to inexperience

Wraith, Changeling, Vampire and blob have no way to be tested.
Murder box is ment to be a pvp mode...
