Split HomeController.cs Sections to Separate Files

[kkevn]

Edit - 6/9/2022: Updated issue to mention administrator related items.

The HomeController.cs file contains many methods and is a lengthy file. It is divided into a few sections also containing items pertaining to creating/removing/viewing/etc... of:

• friends of current user
• games of current user
• scores of current user
• administrator access

Ideally, this file should be split into a few separate controller classes to improve readability:

• moved friend-related methods to FriendController.cs
• moved game-related methods to GamesController.cs
• moved score-related methods to ScoresController.cs
• moved admin-related methods to AdminController.cs
