v1.2.3: add arg to fix framebuffer not redrawing

on some devices, the framebuffer will not redraw unless something is written to stdout, so the arg 'force-stdout' has been added to write spaces to stdout after every key press or touch event

+### Troubleshooting
+
+If key presses do nothing, that is, if on the lockscreen, despite key presses (physical or of the OSK), nothing happens (no asterisk characters show up), try adding the `force-stdout` arg. For example:
+
+```
+ming force-stdout
+```
+
+Or:
+
+```
+ming touch force-stdout
+```
+
