Trial fix for ticket:45
Changed interpretation of second argument to gr_buffer_add_reader from
"history" to "nzero_preload". If the argument is 0, no zeros are
preloaded into the buffer. This is a less surprising interpretation
than the old behavior, which when passed a zero, inserted buffersize-1
zeros ;)
