evil-qemacs/input.c
Charlie Gordon 28397f424f moved input_methods to QEmacsState
qe_register_binding takes ModeDef* and returns status
cosmetic changes in QEDisplay API
added int dpy_init(QEditScreen *s, QEDisplay *dpy, int w, int h);
  copies *dpy (or dummy_dpy if NULL) to QEditScreen and calls method
simplified dpy_init methods and calls
inlined 5 more methods
moved dummy_dpy to display.c and simplified
simplified to_hex
simplified qe_colors array handling
