Title: Negative values in menu

This patch fixes editing negative "minValue" in the menus. Without this patch, negative values would show up fine in the menus, but result in corrupt display during editing.

For example, you'd use negative values when the extruder is being used as a Z probe: MSG_ZPROBE_OFFSET range from -2.0 to 50.
