Documentation of the peap module

[Fabio]

Hi,
first of all thanks for your great GPL'ed RADIUS server!

Looking at the eap.conf file I see that the following options present in
rlm_eap_peap.c:

use_tunneled_reply
copy_request_to_tunnel
proxy_tunneled_request_as_eap

are not documented as the options in the ttls module.

Can someone add the doc to eap.conf for the peap module (for the first two
is sufficient a copy and paste from the ttls module)?

Thanks.
