[glob2-devel] explorers behaviour and conversion behaviour changes

[Nuage]

Hi all, I have made these changes:

-The explorers are now trying to explore the oldest unchecked area. As usually,
I added some random fancy behaviour, so they don't behave deterministicaly at
all. They are meant to explore the cloest area more likely too.

-The unit get converted to another team more likely when it really have the
food. This make the conversion harder but more fair I think. In the old
behaviour you could see some units which would get converted, but won't go to
the other team to eat! Actualy this can still happen, but this is incredibley
less likely to happen.

Please report cons and pros, thank you!
