Lugdunia cave doors

[tchegito]

Reported by Louis H:

In the first episode, when hero gets back to the cave of Ludgunia after taking the moon fragment, he's blocked by the door on the inside.

There's actually 3 problems here:

• hero blocked (obviously !)
• sound when hero walks on already pressed button
• sound when he pushes the door having a key with him

In two last cases, no sound should be heard.

Fixed in 2.50
