Add support for mac extensions
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
File associations on Mac OSX. It would be great if we could associate Paraview with file extensions (like .e) on OSX and have it automatically launch Paraview and try to open the file if we double click on a file with that extension (or use "open something.e" on the command line). Currently I can get it to launch Paraview, but Paraview won't actually try to open the file.
