[phpOpenTracker-general] re: returing_visitor cookie problem

It turns out that a cookie is not set if you have your debug 
configuration set to "2" like I had.

The reason being that the debug routine makes a DB query and pushes its 
message to the browser thus ruining it for PHP's setcookie function 
which is called by the logging engine. The reason that I didn't see 
this at first is that the error is suppressed by an "@setcookie" call - 
causing it to fail silently.

One might want to note this in the docs or, better yet, setup a wiki so 
that I can make the note myself ;)
