Shortened GameManager::IncrementPoints.

-IncrementPoints used to work by having two ifs that calculates score in
the exact same way and then adds the point to the correct player's
score.
-Changed this so that the points are put into an int32_t ( outside any ifs )
-After the socres have been calculated, the scores are added to the
right Player decided by an if
Improved logging

-Added bools for logging to cout
-Added bools for logging to file
-Added function CreateFile() that inits a file and prints a header to it
-Made GameManager::PrintRecv non-const so that it can use the Logger
