Basic game creating API (#2)

* Adding the base of our API

* Little file and lint adjustments

* Adding the lint command to Makefile

* Adding the Minesweeper logic for game creation

* Adding some tests for the Minesweeper algorithm

* Adding some tools command to Makefile like pre-commit and pip-tools

* Adding test help text to Makefile

* all new user is_staff=True, for development for now

* Now we can get the data from specific game
