Subject: new lock-free lifo and fifo fixed buggy unbinding of receive symbols
 no more static assignment of symbols (problems with Metrowerks) fixed bugs in
 SIMD code for non-power-of-2 lengths Max: use high-priority click instead of
 qelem for message-posting added method for clicks into object box
