some improvements

Hi,

Thanks for a great extension! I have been trying to set up auto-minification with various extensions for a long time, but this one has worked out really good for me. It is easy to use and does this job without breaking the registered JS or CSS.

I have made a couple improvements and would like to propose to include these into the master code. The changes have already been tested.

Let me know if you need more information on the changes introduced.


Best regards,
Anton
