fix for a bug reported by zapman on blenderartist.

De-activating a loop-end actuator didnt work (it kept looping).
Looked into this further and it turns out that the actuators run with both positive and negative events false, the sound actuator assumes because its not negative that its a positive event and plays the sound anyway.

Fix by checking that its a positive event before playing.

The size limit on the message actuator was 100 which broke some scripts, set to 16384 instead.
