Add new accessories and characteristics

Hi all,

Please note that in the upcoming Cmd4 version 8.0 only Platform defined Cmd4 accessories will be allowed. (No worries. This is probably everyone). This is because of Homebridge deprecated templates.This will also make homebridge-ui easier to implement. In short this is allowed:

"platforms" :
   [{
         "platform": "Cmd4",
         "accessories" :
         [{
              "type":                      "Switch",
             ...

This will not be

"accessories": [
       {
          "accessory":                "Cmd4",
          "type":                     "Switch",
         ...

Now onto the good stuff ...
Cmd4 version 7.1 now supports the following new accessory types:

• AccessCode
• FirmwareUpdate
• TapManagement
• WiFiTransport

Cmd4 also now supports the following new characteristics:

• AccessCodeControlPoint
• AccessCodeSupportedConfiguration
• AirPlayEnable

• CryptoHash
• FirmwareUpdateReadiness
