stop bot when bag is full

In last weeks's release, I added the function to stop bot once bag is full, which should make the bot safe.

Then I got this email: "zolofighter stops after a few minutes, I don't have a sales waypoint ...... the logs it says thread stopped". I was confused and thought he was doing some customized scripting and caused the bot to throw an exception.

Turned out he is leveling his low level toon and his bags were easily filled up.

So for lower levels, leveling up is much more important than trash drops. They don't care about if bags are full or not, They don't care about drops period.

Another config util entry has been added, it is a drop down to select if you want to stop the bot after bag full or not.
