Fixed MassStorage based demos and projects resetting the SCSI sense values before the command is executed, leading to missed SCSI sense values when the host retrieves the sense key (thanks to Martin Degelsegger).

Added missing DataflashManager_CheckDataflashOperation() function to the MassStorageKeyboard demo, removed redundant SCSI_Codes.h file as these values are part of the MassStorage Class Driver.

Update all demos, projects and bootloaders to indent all function parameters, one per line, for better readability.

Add missing const qualifiers to the demos.

Indent core library function parameters so that there is only one parameter per line, to increase readability.

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.

Increase timeout of Mass Storage and Still Image host commands to 10 seconds (up from 5) to account for slow-processing devices.

Added brace guards to macros with parameters to prevent unintended changed evaluation of the macro expression.

Minor code cleanups (remove redundant comments, fix spacing, etc.).

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.

Split out common defines/types from class drivers into a seperate common class driver directory.

Make central USB Class driver dispatch headers, used for both device and host modes.

Move new Class Driver powered demos to a new ClassDriver subdirectory, re-add old low level demos to a LowLevel subdirectory.

Commit of new class abstraction APIs for all device demos other than the MIDI demo - not documented yet.

Removed scheduler and memory allocation libraries.

Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).

Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.

Moved out each demos' functionality library files (e.g. Ring Buffer library) to /Lib directories for a better directory structure.

Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.

Added DataflashManager_WriteBlocks_RAM() and DataflashManager_ReadBlocks_RAM() functions to the MassStorage demo, to allow for easy interfacing with a FAT library for dataflash file level access.
