fix when using a port other than 80

Hello :)

Today I upgraded our flyspray setup to latest svn.
I had a problem : the site starts to load and stops during loading : the
browser waits indefinitely.

Here is the fix I found :

In the file includes/constants.inc.php :

20,22d19
> // gaboo 20060921
> $_SERVER['SERVER_PORT'] = '81';
> // gaboo

(taht is, just before the line "$baseurl =
rtrim(Flyspray::absoluteURI($webdir),'/\\') . '/' ;"

I believe there's a better way to fix this, hope it will be easier to find
with this :)

Oh, I'm using svn revision 824. But the problem was already there around
revision 780 (I don"t remember which one exactly).

A couple more bugs got fixed, everything more polished, flyspray 1.0 gonna
rock !
