Redirect std::cout to both Debug and stdout

[aryanbaburajan]

Is your feature request related to a problem? Please describe.
As of now, once an instance of Engine has been created, all std::cout and std::cerr logs get forwarded into the Debug class, instead of the default stdout/stderr. Though it's useful, it removes the ability of users to debug log normally, especially in scenarios where the Editor isn't open, or the Debug panel is inaccessible, for example in a released game distribution.

Describe the solution you'd like
Copy std::cout/std::cerr instead of simply forwarding, so that it is forwarded to both stdout/stderr (otherwise, the terminal window), while also being logged in the Debug class.

Hey, could I be assigned to this?

Due to the one std::streambuf limit per std::ostream, logging has been split into two.
Printing to std::cout and std::cerr outputs to the default stdout (terminal), like normal.
Printing to engine.debug outputs to the Editor's built in Console.

Example usage:

engine.debug.err << "This is an error\n";
engine.debug.log << "This is a log\n";

Styling based on log type yet to be implemented.

On second thought this looks possible to me now. I'll give it a try soon.
