Have some improvements on Windows: context

[Mihai Nita]

First: thanks a lot for you great library, saves me a lot of time!

I have started something similar, but Windows only (one can always use
ANSI strings on Mac/Linux).
I wanted to solve two main things: colored output, and better Unicode
output than the normal Java one.

Then I have found you wonderful library, cross-plarform, and solving a
big chunk of my problem.
And I noticed that you also added (recently)
org.fusesource.jansi.internal.WindowsSupport.writeConsole
But there is no way to determine if the output is redirected or not.
Hence this post :-)

I think that when you try to writeConsole and your re-directing, the
API call fails and in turn generates an exception. It's been a while
since I've played with it tho, I might be wrong.

Nothing happens when you redirect (no output, but not exception
either)

The implementation I used in my (abandoned :-) library was using
- WriteConsole without redirect
- Java.out (with Java.setOut("utf-8") first) for redirected output
(hence the need for isatty)
