(legacy) fix notices on IPv6.inc, we should replace this with https://pear.php.net/package/Net_IPv6/download/1.3.0b1 for 16.1 (but there are some other small changes as well there)

Removed width=100% and set inline style="max-width:100%; height:auto"

Added autocapitalize="off" autocorrect="off" to the input for the logon form usernamefld. When using from an iPhone/iPad the first character of the username is capitalized automatically.

While there, make the script run from a secure shell as well.

Keep a symlink on the true file system underneath MFS to keep
pkg(8) operating correctly all the time.

Switch off warnings by default, we just did enable them in master
by default.

leaving out the excessive use of html tags in the descriptions.
