Before, pyb.stdin/pyb.stdout allowed some kind of access to the USB VCP device, but it was basic access. This patch adds a proper USB_VCP class and object with much more control over the USB VCP device. Create an object with pyb.USB_VCP(), then use this object as if it were a UART object. It has send, recv, read, write, and other methods. send and recv allow a timeout to be specified. Addresses issue 774.
