[Martial Arts] Technique to offset -4 for grappled

[JoelSammallahti]

Thanks, mate, for digging those up! Very edifying. Eliminating the penalty seems right out, but I might still go with Dell'Orto's option b) and cap the technique at Skill-2. (I think there's some confusing stuff in there, though - I don't think anyone would suggest a technique actually making fighting while grappled easier than ungrappled, just not as difficult as without specific training.
