LogStream: Add a simple-ish mechanism for colorizing and styling output.
Meet TStyle. It allows you to write things like this: dbg() << TStyle(TStyle::Red, TStyle::Bold) << "Hello, friends!"; Any style used will be reset along with the newline emitted when the dbg() temporary goes out of scope. :^) This can definitely be improved, but I think it's a decent place to start.
