Minor tweaks to the library documentation.

Spell check code and manual pages. Remove custom Doxygen CSS stylesheet, as the new 1.7 Doxygen's default stylesheet is much better.

Add svn:eol-style property to source files, so that the line endings are correctly converted to the target system's native end of line style.

Added new EVENT_CDC_Device_BreakSent() event and CDC_Host_SendBreak() function to the Device and Host CDC Class drivers.

Remove accidentally duplicated model-specific peripheral driver files.

Add more include protection macros to give the user warnings when they try to manually include private driver header files, instead of the public driver headers.

Fix AVRISP-MKII clone project's TPI Chip Erase command processing - ensure erase location is the high byte in the given address space, check NVMBUSY for completion rather than the NVM Bus Enable bit.

Change If-Else chains over to switch statements in XPROGProtocol.c for clarity.

Fixed incorrect interface values in the VirtualSerialMouse and KeyboardMouse demo class driver structures.

Added caveat information to the CDC device class driver.

Added support to the MIDI Class drivers for packed data, where multiple MIDI events are packed into a single USB packet. Added new MIDI Class driver flush routines to override packing behaviour.

Fix MassStorageKeyboard demo USE_INTERNAL_SERIAL check being performed before the required library headers were included, causing a compilation error.

Added notes to the class driver functions indicating which functions require what Device/Host state machine states to function.

Add to the existing CDC Class Driver's CreateStream() function documentation to explicitly state that the created streams are bidirectional.

Fix doxygen documentation - doxygen was getting confused on the variable-length ATTR_NON_NULL_PTR_ARG() macro used on  function prototypes and was generating many return types for several functions in the documentation (thanks to David Lyons).

Added new stream creation function to the CDC Class drivers, to easily make standard streams from CDC Class driver instances.

Add optional double-banking support to the Device mode Class Drivers, on a per-endpoint, per-interface level.

Make MouseHost and KeyboardHost ClassDriver demos use the HID Class driver's structures for the boot protocol Mouse/Keyboard report data, rather than rolling their own.

Prevent the CDC Device Class driver from sending empty IN packets on every service task call - only send termination packets when data is in the endpoint.

Add StillImage Host Class Driver functions for opening and closing sessions. Ensure IsActive is set on the interface to allow device functions to run.

Fix spelling of "Received" in all source files where it is misspelt "Recieved".

Added  ATTR_NON_NULL_PTR_ARG() attributes to the class drivers to improve user code reliability by disallowing explicit NULL pointers as pointer parameters in function calls where the parameter must not be NULL.

Disabled building of the Demos/Host/ClassDriver directory until Host Mode Class drivers are complete to prevent build errors in the meantime.

Minor updates to the unfinished SideShow demo for clarity.

Added unfinished MassStorageHost class driver demo.

Minor documentation fixes.

Renamed all library events to properly seperate out Device and Host mode events. Changed the firing conditions for some events to ensure that events are fired by their own USB mode only.

Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.

Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.

State information for class drivers is now zeroed out during enumeration (both in device and host mode) to ensure sane values after each enumeration. User code should no longer explicitly set state information as this is no longer preserved.

Added parameter directions to function parameter documentation.

Added new experimental FAST_STREAM_FUNCTIONS compile time option to speed up stream transfers at the expense of a higher FLASH consumption (needs testing to verify improved throughput).

Added USE_INTERNAL_SERIAL compile time option to automatically read out the internal unique serial number as the device's serial number descriptor on supported AVR models.

Break device mode class driver interfaces into seperate config and state structs which are then combined, for clarity. Move device mode class driver interfaces back into the device mode class driver headers from the common class headers to make room for host class interfaces.
