autolaunch: added param for delay

launchdetector: return state of detection

The launchdetector now has a intermediate state (controlsenabled) which
is meant to be interpreted by the controller as: "perform attitude
control but do not yet power up the motor". This can be used in the
floating phase during a bungee launch for example.
fw pos control: use new lauchdetector states
fw pos control: set default roll, pitch while waiting for launch
fw pos control: launchdetection logic cleanup
fw pos control: set pitch sp correctly while waiting for launch
