fookb: Port to libdockapp.

Browse source 
In addition to the obvious simplification to the code by removing all the
window creation stuff, this also allows us to let users pick whether they
want to run fookb as a dockapp or as a normal windowed application at
runtime using libdockapp's --windowed command line option.  Previously,
this was done during build using configure's --enable-wmaker option.
