Department icons are not aligned on a grid

Using the current bzr version icons are not aligned on the departments grid, it's easy to get a different number of icons by lines by changing the dialog geometry

This could easily be fixed by someone who knows CSS: basically each item (icon + name) needs to be a {display: inline-block;} element that has a consistent width, regardless of the length of the name. (I've just clarified in the spec <https://wiki.ubuntu.com/SoftwareStore?action=diff&rev2=159&rev1=158> that long names should be ellipsized in the middle; you could achieve ellipsis at the end at the same time as fixing this bug, by setting {text-overflow: ellipsis;} on the element containing the name.)
