Bug fix and design

V0.1.2 was exclusively for bug fix and design.
Between the old versions I noticed bugs which I fixed to an high amount.
Also I redesigned some things like the main menu or the pause menu and the design for the 7x7 grid.
Now the code runs smoother and if we ignore the resize option the code is free from unwanted possibilities.
If you find one, please say it, that I can fix it as well.
