Fixed HID Parser not distributing the Usage Min and Usage Max values across an array of report items.

Browse source 
Added new HID_ALIGN_DATA() macro to return the pre-retrieved value of a HID report item, left-aligned to a given datatype.

Added new PreviousValue to the HID Report Parser report item structure, for easy monitoring of previous report item values.
