Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Browse source 
Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.
