Bump version to 1.2

Been too long since a version bump, so 1.2 is born.
Changes:
* Bazle support for building the Android companion app
* Precondition checks for handlers to avoid loading if required files
  aren't present.
* Support for -x/--extrasdir to specify the location of required files
  (such as trusted-cert.pem, replace.png, etc).
* Improved some documentation
* Detection of weak ciphers such in client connections
* Detection of devices with the superfish CA installed
* More support for parsing TLS records
* Exciting bug fixes for some uncommon blocking conditions
