Fix just shows escape code instead of colored text on Windows 10 Console

[gaeulbyul]

On Windows 10, just shows escape code instead of colored text.

According to ansi_term crate's README, Application must enable ANSI support for print colored text on Windows 10 Console.

Note for Windows 10 users: On Windows 10, the application must enable ANSI support first:

let enabled = ansi_term::enable_ansi_support();

This commit add ansi_term::enable_ansi_support() into active function.

Thank you very much for the PR! I moved the activation code into the run function, so that it's only ever run once.

I'm eager to support Windows users as best I can, so please don't hesitate to report issues as you encounter them.

I have pushed a new release with the fix: https://github.com/casey/just/releases/tag/v0.3.8

The release will be updated with binaries when they are built on Travis and Appveyor.

Hello, I tried released version (v0.3.8) but same issue reappeared again. but, if I input just --list --color=always, just shows color correctly. Other command shows escape code.

Hmm, very strange. Was it an issue with the changes that I made to your code? Did your version work consistently? I don't have access to a Windows 10 machine at the moment, so it's hard for me to test.

Yes, my version works well. I don't know why it broke again... 😕

Hello, I tried your win10 branch. just --list (without --always option) shows color correctly. but error meesage (just fail) still shows escape code.
However, if I put one more enable_ansi_support() after justfile.run()(src/run.rs:358), error message shows color correctly. putting it before justfile.run() does not effect.
