Beta3: Colored console output is now *optional* and disabled by default on Windows.

Made a small update to make PHPloy more approachable for Windows users -- colored output is now disabled unless Ansicon is detected.  Colors can also be disabled by using `--no-colors` command line option (may be useful for other tools and scripts that prefer plain text output).  When colors are disabled, the tags are simply stripped from the output.  

This functionality has also been moved to a static class, and is now available [elsewhere on Github](https://github.com/SimonEast/Simple-Ansi-Colors).

Are there a couple of people that can test for any regressions before we merge?
