Properly parse web hostname from sbbs.ini

Get both the webroot and web hostname from sbbs.ini rather than use
system.inet_addr.  system.inet_addr is configured in the messages
section, so it's implied that it's for email addresses.

Also, allow configuring the sysop email address with the SysopEmail
global key in the ini file.

This is a cleanup and duplicate of !82
