Not compatible with php5.5+

[Mouradif]

Hi there

This project uses a custom class called Generator. Under php5.5+ this class name is reserved and can't be redeclared. Fortunately, there's only two lines in one file (GameEngine/Generator.php lines 12 and 159) to edit to fix this by renaming the class and using the new name in its instantiation.

As for php 7, all mysql_ prefixed functions must be removed. That's a much harder task to perform but if pull requests are welcome, I might get to it since I will be running this script on my server under php 7 if possible (I'm currently testing it under PHP 5.6 after renaming the Generator class)

Fix for 7 would be nice.
Even as Fork!
