Two Bot Issues

[Nibiuno]

I've run into a couple of issues, one that causes world.exe to crash, and another that bugs groups until a server reset or manual deletion of group information in the database.

If someone with bots out starts an adventure, it crashes world.exe. I believe adding a IsBot() check to the code that creates an adventure would stop it.

The other issue is if you have a group with bots and one client leaves the group, a bot can end up with group leader. This bugs the group completely and the person who is still in the group is bugged and cannot join other groups, even after disbanding.

I think the group code also needs a bot check before assigning leadership.
