Subject: Added global highscore list

You can now view and submit highscores to the global highscore list. If the connection fails, you are allowed to retry sending it so your score is not
lost. The actual global highscore list is a PHP file and MySQL database that will need to be uploaded to Four Island Other for this to work.

Some other things were done. Because it was discovered that the frequent window caption changes were making Maze Of Life crash, they were removed and the
player is now notified of their score by the level number appearing in 100 point font at the beginning of each level during the doneWorking stage. Also,
a cheat was added that allows you to play the game in fullscreen if you press F4 on a supporting platform. The player is now also slightly faster.

Closes #104
