Ticket #1017. Put a @ before each fwrite to silence errors. Also setup the log file in the beginning rather than on each individual function.

Resolves #1018. Provide a more unique host name for the file.

Add workaround for referrer check to not be triggered on the previous IP address when redirected by the setup wizard.

Redirect to the correct IP at the end of the setup wizard if accessing it on an IP address that was changed. Fixes #455

Fix typo in comment.

Ensure this is an array before entering the foreach loop. Fixes #1012

Avoid exec() and use php calls.

• Use pkg_info -E pkgname* for testing if a package is installed.
• Do not call eval if we cannot include an .inc file since that will make the whole script fail.
• Keep the log from the start to the end without overwriting. This makes debugging and problem reporting easy and explains what is done during installation....
