Subject: Beta 4

- now supports 'native' Linux /dev/spi* interface and SPI-over-USB using FTDI bridge through libmpsse
- Flexible build system, with library.cfg file to set Makefile options
- removed 500 kHz bandwidth limitation on radios, pushed it to the nominal 800kHz usable bandwidth
- RSSI calibrated fo Lora multi-datarate channels
