Pekala, bu büyük bir commit...

Daha önce bahsettiğimiz config sınıfının bir instance'ının tüm süreç
tarafından kullanılması esasına dayanıyor. Config yerine bir
"context/bağlam" yaratılıyor ve tüm sabit(constant) ve değişken
yapılandırma seçenekleri (PSPEC dosyası da dahil olmak üzere) bu bağlam
üzerinden taşınıyor.

Biraz daha düzenleme gelecek. Çalışan bir sürüm çıkarttığım için commit
ediyorum.
