wonx/WWCharacter.c
Hiroaki Sakai eb06f7f4f8 Added text display function. (Only 0 to 127 ASCII characters, kanji is not supported)
Changed to create Wonx class and manage all resources with Wonx class.
(See Wonx.x WonxP.h)

When p is pressed to switch display / non-display of the screen, redraw the LCD panel
Improvement.

Added -Wall to compile option.

We have summarized the processing part of the function which is duplicated processing in disp.c.
