[dokuwiki] Ignoring all files/dirs that match a given RegExp (e.g. ^CVS$)

Hi, 
As I keep all pages and media files of my dokuwiki installation in CVS, I have 
a directory named CVS in every directory. Now, of course dokuwiki understands 
these as namespaces and shows them in all namespace lists.

Attached is a patch for the latest stable version ( 2006-03-09b ) which adds a 
configure key that holds a RegExp that will be used to ignore matching 
dirs/files.

So, if you add 
  $conf['ignorepattern'] = '^CVS$';
to your conf/local.php, then all CVS/ directories will be ignored 

Cheers,
Reinhold
