outfile name is overwritten by sourcefile name

Hello,
the out file name is set to source file name causing source files to be overwritten. This seems to happen in lines 769 in class.magic-min.php where $minfile->references was set to source file name in minified_filedata. This applies to version 3.0.3 (master branch).

Still happens unless you use the HASH file names
