Added game settings window

Adds what the window where the user is able to create a game. It is not currently finished as it needs to have some other fields added and has no functionality. 

This basic GUI is currently not functional, but simply provides the basic layout that it will follow. This includes a place to type the name, a drop down menu for selecting a long or short term game (live or not), and selecting the deck of cards that will be used for the game.

There are two boxes that will hold the requirements that can be selected and one for the requirements that have already been selected.
