Testing RH_RF22 with RFM23BP and 3.3V Teensy 3.1 and 5V Arduinos.  Updated documentation with respect to GPIO and antenna control pins for RFM23. Updated documentation with respect to transmitter power control for RFM23
Fixed a problem with RH_RF22 driver, where GPIO TX and RX pins were not configured during initialisation, causing poor transmit power and sensitivity on those RF22/RF23 devices where GPIO controls the antenna selection pins.
