Added support for ANSI color codes to logged terminal output.

[greggbjensen]

.NET Core outputs ANSI color codes for it's standard logging, and these are not currently translated. This leads to output that contains unprintable characters.

Adding support for ANSI color codes will allow for more readable logs, and consistent support for .NET Core as well as other applications.
