core (logs): integrate Kivy logs with SàT: - forbid kivy to handle its own logs - added log_kivy_level option which can be put in sat.conf in [cagou] section. This option can have the following values: - follow [default]: follow SàT cagou level - kivy: follow level set in kivy own configuration - [log_level]: set this log level only for kivy messages
