Bluetooth demo can now create and maintain logical channels - need to determine why Windows machines refuse to connect.

Make Bluetooth signalling handler routines use the generic Bluetooth_SendPacket() routine for their responses. Use a better method of controlling the debug output verbosity.

Add bidirectional channel configuration -- remote device is not ACKing sent Configuration Requests, needs further debugging. Implement Bluetooth spec's channel states.

Use abbreviations for the structure and function names where possible to try to cut down on the code verbosity.

Ensure that the AVRISP-MKII project's Windows avrdude compatibility define is named properly in all parts of the code.

Add Bluetooth connection request/complete/disconnection callbacks.

Remove debugging from HCI layer, as it is now operational -- add guards to ACL debug statements to reduce logging chattyness so that the overall command sequences can be observed and debugged.

Remove unused macro in the host mode demos for the maximum Configuration Descriptor size.

Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.

Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.

Changed per-device controller preprocessor checks over to per-device series for better device control.

Fixed error in Endpoint.c using HSOFI rather than SOFI for counting elapsed milliseconds.

Copy and convert incomplete Bluetooth Host demo to the library.
