Include `.deb` files to the release files

[tapyu]

There is an open issue in deb-get considering the inclusion of HDFView. However, we do need to have a direct URL for the uncompressed .deb file of HDFView in order to include it to deb-get. At the moment, the .deb file for Linux is compressed in a .tar.gz file. Can you consider releasing a .deb file solely so that deb-get can handle this installation automatically for Linux systems?
