For act and speech triggers to operate, act() must be called for them even
though they are descriptorless. This being the case, however,
write_to_output () shouldn't be called for them.

Looks like for the reference patch, I missed a line that's in my mud. In
perform_act(), 3 lines from the bottom is a call:

     SEND_TO_Q(CAP(lbuf), to->desc);

simply add

    if (to->desc)

before it to fix the crash.
