Blank page when this plugin is active

Hi, I had my wordpress admin show a blank page when doing some operations and could trace the problem back to your plugin.
The problem was that your plugin was outputting some characters when starting up. It turns out that your php files had some newlines after the ?> closing tag. To solve completely the problem, remove ?> at the end of the file, so if some characters slip in no output is generated.
The problem probably only happens when having output_buffering off, but I think the fix is easy enough to be applied.

Thanks
