Synchronization doesn't allow bulk operations

[Ben Gamari]

I was very disappointed to find that the interface exposed by software-center to the oneconf facility is effective unusable due to the inability to perform bulk operations on groups of packages. That is, software-center shows a nicely formatted list of the packages present on a remote machine and not on the current installation, but there is no way to install the elements of this list without manually installing each one.

<https://wiki.ubuntu.com/SoftwareCenter#oneconf> specifies an "Install All" button next to ‘{number} items on “{name of other computer}” not on this computer’, and a "Remove All" button next to '{number} items on this computer not on “{name of other computer}”'.
