Excluding players with specific prefix

[ph59x]

In some server, fake players are used widely. Usually they have a same prefix ( like "bot_", if correctly configured in carpet mod ). Most fake players have abnormal statistics. For example, the longest online time, mostly much longer than any other player.

Hello, and thanks for the contribution! I won't merge this for two reasons:

• The entire config structure has been changed. That will make the existing configurations invalid, so if you already have a config and update MinecraftStats, it won't work anymore. This is what the config version was intended for, but I don't think a minor feature like this justifies a breaking change (it has never been requested, so many people probably never heard of this issue, including myself).
• The Java rewrite of MinecraftStats is almost done. I don't really intend to maintain the Python version after that. Due to its simplicity, however, I will include this feature in the Java version (albeit without any breaking config changes).
