#36 CGIEnv don't work

[Michele d'Amico]

The CGIEnv option in config file don't work properly.
The root cause of this bug is that the conf file is
read before that the common_env array is created. That
behaviour is correct but the actual implementation of
CGIEnv could not work.

I've produced a patch that is attached (apply it to
boa's root directory).
Enjoy and test it... that patch work well for me

Please, don't hesitate to tell me any dubt...
(Sorry for my "poor" english)
