General code cleanup (removing extra tabs/spaces)

[chris-gong]

This is more of a reminder for myself, but for some reason, not sure if this is a Unreal Engine thing or a Visual Studio thing, but when I define member variables that are labelled UPROPERTY in a header file, those member variable definitions get an extra tab of space by default. After part 11 of the tutorials is finished, I think I'm going to just get rid of these extra tabs in all of the header files. In addition, I think that I should get rid of extra tabs and spaces, specifically in the GameLiftTutorialCharacter.cpp class, but also in other files where this occurs. I believe that the last point has to do with normalized line endings but I could be wrong.

Closing this because I no longer think this is that high of a priority, but I may do this in the new feature branch.
