fcce354 fix git checkout bug through suppression

Discussion
----------

Fix git checkout bug :: git checkout returns STDERR instead of STDOUT

When building a project stderr is returned by git when it intends stdout. Following command prints to stderr and causes error
```
$ git checkout 'origin/master'
    HEAD is now at 43329a9... update MongoRecord
```

Dumping $process

// Builder.php::execute() | var_dump($process);

Surprisingly adding `git checkout -q 'origin/master'` will suppress that error yet still return stderr. After browsing the net there are a number of issues where git uses stderr instead of stdout.

This will need others to test and look into to determine if it has to do with my version of git.

`-g` is not a valid switch for `checkout` (at least, not for me: git version 1.7.11.3).

Sorry that was a typo meant `git checkout -q`
