well I found the servo that caused (I think) the problem but I don't know how or why it could do this it has ran great for at least the month i have had it...This is the neck servo ...and no the cable was not crushed between the servo and hinge point I thought that would have been the cause also...honestly this has been running fantastic up to this point..I am confused *confused* *sick*

Awe man, how unfortunate!

If a servo runs past it's physical ability to move, it will cause a short - this is an un-avoidable result of a servo moving too far in one direction. Referencing the photos, you will notice the neck servo is moved far too forward, which is further than it can physically move.

Motors will "spin" no matter what - so if you stop it from spinning, it will burn out - which is what happened.

You will surely need a new neck servo - and also any other servos which have burned wires. Don't think i've seen destruction like that before! It does suck to experience your first burn-out, but be proud that you did a great job at it!:D

Thanks! I'm quite impressed as well. It's such a rare occurrence for something like that to happen from a stuck servo. Usually the servo smokes, never the wires. This is a first!
