releasing version 8.82

* Use debhelper compat level v7 when building packages. All changes
  since v4 seem safe for alien's generated rules files.
* Use dh_prep instead of deprecated dh_clean -k.

+  * Suggest lzma. If not installed, alien will still fail to decompress
+    RPMs using it, but will support most rpms, which are not.

+    was about the "expire" it 4 days from now. We got lucky Duane, but please
+    use the Debian BTS next time!)
+  * Support RPMs containing ghost files.
