Removed all binary constants and replaced with decimal or hexadecimal constants so that unpatched GCC compilers can still build the code without having to be itself patched and recompiled first.

Move StdRequestType.h, StreamCallbacks.h, USBMode.h from the LowLevel USB driver directory to the HighLevel USB driver directory, where they are more suited.

All comments in the library, bootloaders, demos and projects have now been spell-checked and spelling mistakes/typos corrected.

Fixed USBTask.h not conditionally including HostChapter9.h only when CAN_BE_DEVICE is defined (thanks to Ian Gregg).

Fixed incorrect/missing control status stage transfers on demos, bootloaders and applications (thanks to Nate Lawson).

Updated makefiles to reflect new dfu-ee programming target invocations (supplied by Opendous, Inc.).

Renamed the ATTR_ALWAYSINLINE function attribute macro to ATTR_ALWAYS_INLINE to match the style of the other function attribute macro names.

Added ATTR_ALWAYS_INLINE attribute to several inlined library functions, to ensure they are inlined in all circumstances.

Cleanups to Endpoint.h and Pipe.h. Added better documentation for the endpoint and pipe interrupts.
