Version with confusion not working

Commit to show christopho the code and try understand why it is so messed
up.
New version of confusion, must be tested.

Should at least enable the false direction without problem. Maybe a
problem could occurs to stop, not sure.
Confusion WIP

Hero is going on the good way, but he never stops. Think the trigger
release is never called because of the previous
simulate_command_released...
Confusion is now OK

When you are confused while walking, the direction change automatically.
When you are healed from confused while walking, the direction also change
automatically. Next step : allow to customize the mix of directions to do
a random confusion.
