dd support for a USB keyboard as the NxConsole and text widget input.  Not fully functional as of this initial check-in.  Basic functionality is there, but there are conditions were the keyboard gets lost.

NxPlayer needs to set curbyte field to zero before enqueuing a buffer.  Otherwise, it looks like beginning of the buffer has already been consumed

Audio:  Add hooks for fast-forward and rewind needed by CMediaPlayer; add hooks for equalizer settings needed by the WM8904

NxWM: Beginning integration of NxPlayer into Nxwm::MediaPlayer. Gets handle, sets device, and releases handle.  Lots more to be done

NxWM: Increase default priority of mouse and keyboard listener threads. Does not seem to make any difference but still seems like a good idea

Rename CONFIG_NX_MOUSE to CONFIG_NX_INPUT, then add CONFIG_NX_XYINPUT_MOUSE and CONFIG_XYINPUT_TOUCHSCREEN

NxWM::CMediaPlayer:  Fix of state related bugs + Size if CLabel is increased (in preparation for becoming a CListBox)

Add larger images for media player.  Also options to control spacing and borders on media player windows
