If I attach a file containing multiple dots, e.g. foo.doc.pdf, then viewing it in the attachment table fails, with different symptoms in IE and Firefox.

The reason is that the HTTP response has a header "Content-type: text/plain" - IE and Firefox both react at least "unfriendly". This can be tracked down to a bogus regex in lib/TWiki/UI/View.pm, sub _suffixToMimeType which captures everything after the first dot.

There's a one-line patch:

     my $mimeType = 'text/plain';
-    if( $theFilename =~ /\.(.+)$/ ) {

         my $suffix = $1;
         my @types = grep{ s/^\s*([^\s]+).*?\s$suffix\s.*$/$1/i }

We're having filenames with multiple dots quite frequently, mostly coming from automatic document conversion to PDF - therefore I'm setting this to "urgent".

Thanks for the patch, very helpful!
