virtualbox-4.1 deb needs to conflict/replace virtualbox-guest-additions-iso

[Pat Pannuto]

The virtualbox-4.1 .deb package also needs a conflicts/replaces entry for the ubuntu package virtualbox-guest-additions-iso, otherwise the installation will fail:

$ aptitude show virtualbox-4.1 
...
Conflicts: virtualbox, virtualbox-ose
Replaces: virtualbox
...

$ apt-get install virtualbox-4.1
...
dpkg: error processing /var/cache/apt/archives/virtualbox-4.1_4.1.0-73009~Ubuntu~natty_amd64.deb (--unpack):
trying to overwrite '/usr/share/virtualbox/VBoxGuestAdditions.iso', which is also in package virtualbox-guest-additions-iso 4.0.8-1~natty1
...

[Frank Mehnert]

This conflicts entry needs to be added in the virtualbox-guest-additions-iso package (it already conflicts against older versions of VirtualBox).
