Refactor out the Logger configuration.

As this isn't any kind of server-like software, I don't think we need configurable loggers. So I'll be refactoring out logger configuration functionality -- and will bind the console and file log will be just statically.

I'm always loathe to remove functionality and configurable loggers are wonderful for runtime debugging.

That said the overhead may not be worth it.

With the latest commit, I left them as still configurable ones.

Loggers are already initialized by the sample game where modifying the game.cs code and configuring them in-code is just similar to configuring them from the ini file.

And for release builds, I don't think anyone will be willing to let their users to configure game-clients logging functionality from the ini.
