Transfer all functions to util.py

[SepehrRasouli]

Hi Onionj. As a contributor, I've a hard time trying to write new features and I can't use the pybotnet's features so I've to kinda invent the wheel again every time I want to run a command and etc. I would be very happy if you consider transferring all the useful features and their functions to util.py so the contributors wouldn't have a hard time trying to write new and useful features.
