dbbot tests don't work in Windows

[Tattoo]

In acceptance tests, the path to dbbot is resolved wrong. Also, this should point to correct startup script depending on the environment (dbbot.bat in Windows, dbbot everywhere else)

I'm using Windows 7 and copied DbBot-master to my ../../tools directory. When I execute the dbbot.py -f command it returns with the following error "No module named reader". I copied the reader directory to the DbBot-master\bin directory and it found the files but got the following error "cannot import name DatabaseWriter".
