- Added a pre-compiled custom GN3S firmware. - Added a fully-compliant GNU Radio source block for GN3S USB dongle. It can be used also from GNU Radio companion and from Python applications. - Added a new GN3S_Signal_Source block. It is possible to disable the GN3S signal source compilation. See README. git-svn-id: https://svn.code.sf.net/p/gnss-sdr/code/trunk@217 64b25241-fba3-4117-9849-534c7e92360d
