fix (NPCBots) : a few fixes and customization

 - At each level change, the bot's equipment is reset and randomized. So now the bots are no more so powerful, with level 80 weapons!
 - Implemented attack and abandon commands, to force bots to attack a creature or to flee.
 - Minor : at loading, display the location names of the bot, instead of the ids.
