df38ee01ba gui & tnc improvements 
displaying now frequency offset and frequency in heard stations. Decreased size of receiving audio buffer, which seems to optimize RX

655d333af2 freq offset handling #81 
first attempt just with pings. Station A sends a ping to Station B. Station B is detecting RX offset, adds it to the ping acknowledge frame and sends it back to Station A. Station A will then adjust the frequency

e7ccf42ec3 modem optimization 
optimized chunk size for audio data. DATAC3 should now work and overall SNR is optimized since we have less biterrors beacuse of losses by simultaneous buffer allocation

8b08cc6e6b stop transmission 
first attempt with stopping a transmission after the processing the current burst. Logging is a little bit ugly at this point, because it looks like a frame got lost. However, the transmission stops. CLI output is only visible for people interested in debugging...
