[hpsdr] Ghpsdr3 and the Android client

[Sid Boyce]

ghpsdr3-alex supports other hardware besides Softrock.
HPSDR/SDR1000, Softrock, UHFSDR, Microtelecom Perseus, RFSPACE SDR-IQ, 
HiQSDR, Ettus Research USRP, and the rtl-sdr DVB-T dongle.

The first client that connects becomes master and all subsequent clients 
are slaves.

Only the master client has control, slaves can only listen.

What's lacking is there is no way for a client to know whether he is 
master or slave other than that his control commands are ineffective.

In the dspserver log screen locally I will see a report stating that a 
slave client has tried e.g a set frequency command.
