Based on the original idea of Nathan Huesken, which was then implemented by
Gwenhael Le Moine, I completed and corrected the layout.
I added icons for the layout and modified the makefile and the aweseomerc.lua.in
to include the fair layout.
In the process I also decided to modify layoutgen.sh and tag.c, so that in the
future new layouts can be added without touching tag.c.
