Tweaking game settings

For now, the game settings are not provided on the game UI. You can change and tweak some game settings for your convenience by editing certain fields in the code itself. You have to change the values of some variables in the main.go file, as shown below

• Snake speed - It can be controlled by editing the d.TickDelay variable. Its default value is 200, the more the value, slower the game becomes.
• Game Board Dimensions - The board length and breadths can be changed by updating d.M (height) and d.N (width) variables in main function. The default values for width and height are 40 and 20 respectively.
