src/utils.c: Disable canonical mode in press_any_key()
Use tcsetattr() to disable canonical mode in press_any_key() before waiting for a key press. This makes sure that input is available immediately (instead of line by line). Also, disable echoing until a key is pressed. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
