sorry for crash in hf-0.6.4, fixed in hf0.6.5

Hello friends Due to not storing the rx window, after some minutes of rx (depending on amount of data) hf-0.6.4 died of buffer overflow. I fixed that in 0.6.5. The calibration programs have now bettwe output and write the configuration automagically, the mailbox feature has been improved, tested successfully also with repeated connects in Pactor and Amtor ARQ and FEC.
