Couscous deploy should use local account settings when available

[taophp]

Hi,

I just tried Couscous, and I'm very enthusiastic. But I meet a problem.

I have set some account setting locally in the project like this:

git config user.email "you@example.com"
git config user.name "Your Name"

I intentionally avoid the --global option as I use more than one account on the same machine.

The problem is that when I want to deploy with couscous, I got an error:

In CommandRunner.php line 29:

  *** Please tell me who you are.

  Run

    git config --global user.email "you@example.com"
    git config --global user.name "Your Name"

  to set your account's default identity.
  Omit --global to set the identity only in this repository.

  fatal: empty ident name (for <steph@DESKTOP-J1AELFI.localdomain>) not allowed

I hope it could be fixed soon. Thanks for your work, and hold on guys.
