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.).

Fixed incorrect values for REPORT_ITEM_TYPE_* enum values causing corrupt data in the HID Host Parser.

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.
