saving game resolution to player prefs

[ghost]

for now we are getting the screen resolution at intro scene. probably this will work only for this scene , we need to save the resolution to playerprefs , so we can access the game's resolution from other scenes whenever we need that.

here is some hint for player prefs : https://docs.unity3d.com/ScriptReference/PlayerPrefs.html
