[ubuntu-uk] Dummy transitional package

[Daniel Llewellyn]

a "dummy transitional package" is a stub that gets created when a piece of
software changes name or politics cause the packaging to change namespace.
The software gets placed into the new package name and new installs will
get that by default. However, upgrades need a way of not breaking when the
package name it has references to suddenly disappears while it's working.

So the stub is created at the old name which depends upon the new name
thereby pulling the new package into your system. The stub also serves as a
way for other packages that used to depend on the old name but haven't been
updated to the new name to still be installable.
