Title: added FastColoredConsoleTarget

I wrote a new target. It is faster than ColoredConsole, but has fewer features. It is necessary for debugging when you want to display a lot of information to the console without slowing down the program.

In my test, it is 2-3 times faster
```C#
public async Task LoggerTest(ILogger logger)
{
var sw = new Stopwatch();
Console.WriteLine("Start Logger Test");
sw.Start();
var list = new List();
for (int i = 0; i < 30; i++)
list.Add(Task.Factory.StartNew(() =>
{
for (int j = 0; j < 1000; j++)
logger.Debug("Thread {0} - ping {1}", Thread.CurrentThread.ManagedThreadId, j);
logger.Error("Thread {0} - end", Thread.CurrentThread.ManagedThreadId);
}));
await Task.WhenAll(list);
sw.Stop();
//Console.ReadKey();
Console.WriteLine("Elapsed time {0}", sw.ElapsedMilliseconds);
Console.WriteLine("Stop Logger Test");
}
```

I do not know what projects to add target, so only add .net4.5. I hope you will take and do the rest.
Sorry for google translate.
