Add methods for traversing and combining QProcessEnvironment.

New methods that make QProcessEnvironment more friendly. With these
two new functions developers no longer have to resort to using
QStringList and use the deprecated QProcess::setEnvironment() method.

New methods:

 - QStringList QProcessEnvironment::keys()
 - void QProcessEnvironment::insert(const QProcessEnvironment &).
