documentation: stock icons

[Murray Cumming <murrayc murrayc com>]

Since I moved the website, the stock icons do not show up on the stock
IDs page. I think it's because GTK+ changed where they are installed, to
be compliant with the freedesktop specifications. Would someone like to
investigate and fix the build stuff to make this work:
