Need a method to get the current state, and reset the current 
state. Otherwise, nested calls to the console functions will 
screw up the state.

I.e.:

    auto save = getConsoleState();
    setConsoleColors(Fg.red, Bg.blue);
    writeln("Red text on blue background.");
    setConsoleState(save); // Bring back initial state

Or better:

    auto save = getConsoleState();
    scope (exit) setConsoleState(save);
    setConsoleColors(Fg.red, Bg.blue);
    writeln("Red text on blue background.");

On Windows, setting color to initial sets console colors to ones 
that were set before launch of the program. On Posix it sets 
default (ANSI remove formatting).
I will try to check if it is possible to get current colors on 
Posix.
