New stable release of nfcpy - 0.10.0

Written for nfcpy by Stephen Tiedemann on 2015-07-27

The new stable release starts the 0.10 series with increased support for NFC tags and a lot of internal updates geared towards future enhancements. The most visible change is probably that many tags are now known by product and can be formatted (for NDEF), made read-only or protected with a password (for tags that have such functionality). The tagtool.py example supports those new functions from the command line and, for password protection, also does key diversification of a master secret. Other enhancements are that Type 4B Tags are now finally supported, Type 1 Tags can be read with chips that would not normally support it (PN532/533) and the serial connection with a PN532 is run at 921.6 kbaud (Unfortunately the RasPi serial port only goes up to 112.6 unless the serial clock is changed. But with an FTDI it works pretty well).
