RadLog v0.42 restart

Ok. When audio method is selected and logging started, the process priority is set to High. It returns to Normal when logging is stopped.

I'm going to release an alpha version, as there have been so many added features. This means there will be some untested and non-functional parts, but it will at least get some movement going on the release.

Hey Frank
I have to finish sanding a floor in the house, then I will be spending some time on RadLog and radmon.org development. The plan is to tidy up the rough edges on RadLog for an alpha release (add SFTP, extra graph uploads, time sync and conincident stuff tidyup). Development has been stalled for a while due to personal commitments, these are clearing a little so some time can be allocated to radmon.org. Thanks for bearing with me!!!

I'm also hoping with the alpha release, the APRS packet modulator bug may be found... If anyone can work soundmodem on Linux and capture the raw bitstream generated on RX, then your help would be very much appreciated. I suspect the error will either be in CRC generation or packet format.

Right, off to sand some floor..
