When making mockups for GNOME apps in Inkscape, looking for symbolic
icons is a common task. Searching for icons in the file system is clumsy,
and icon-browser provides a much better interface for finding them.
However, currently there is no way to insert the symbolic icons as SVG
directly from icon-browser, so right now it is only useful for finding
the name.
This patch adds a sixth column to the modal window that appears when
clicking a symbolic icon. The icon in this column is labeled "scalable",
and dragging it onto another window results in the vector icon URI being
inserted.
This enables a much simpler workflow when designing with symbolic icons.

Instead of slavishly following the naming spec, group the icons
into categories that are more likely to be useful for application
developers. Based on input from Allan Day and Jakup Steiner.
These non-standard icons were dropped from Adwaita. Eventually,
the icon-browser code should be changed to show all standard
icons + whatever is actually in the icon theme, instead of
hardcoding a list of non-standard names.
