Don't load/list the mail index in reverse (newest-first) order by default.

Unfortunately, the call to readmail() in other places in sbbs
(e.g. logon.ccp, useredit.cpp) is hard-coded without *out* this loadmail
flag, so you get an index in oldest-first order when you logon and answer
"Yes" to the "Read your mail now?" prompt and get the index in reverse
(newest-first) order when you use the 'R' command from the email prompt
which is unexpected and likely confusing to users. Until we can replace
these hard-coded calls to readmail() with scripted logic which can read/
use a user-preference property (e.g. from data/user/*.ini), we will just
default to the old/previous behavior. The user is one key (!) away from
reversing the index anyway.
