.deb lintian issues

From https://bugs.launchpad.net/ubuntu/+source/scala/+bug/1126035/comments/9:

It works as a workaround, but the quality of the upstream package is bad:

$ lintian Downloads/scala-2.11.0.deb
W: scala: control-file-is-empty conffiles
W: scala: copyright-without-copyright-notice
E: scala: description-starts-with-package-name
E: scala: maintainer-address-missing LAMP/EPFL and Typesafe, Inc.

W: scala: extra-license-file usr/share/doc/scala/License.rtf
W: scala: embedded-javascript-library usr/share/doc/scala/api/scala-compiler/lib/jquery.js

After that, Lintian just hangs (which makes it impossible to install it using software center).

FYI: Most of Scala devs are on Mac so we are not familiar with details of Linux tools and ecosystem. However, we're thrilled to take patches.
