Make Query Generators Into Dynamic Modlues

Move bingQueriesGenerator to queryGenerators folder
main.py add queryGenerators folder to PATH
Add <queries> tag to config file
Modify config.py to read <queries> tag
Make bingQueriesGenerator dynamic loadable
yep, looks good. I think it shouldn't be to much of work there. Empty **__init.py__** in every folder should do the trick
