If there is no config-file in $HOME, use a default parameter value
instead of complaining and exiting.

Now that we use libdockapp's --windowed option to allow users to choose
whether to run fookb as a dockapp or as a normal windowed application at
runtime, the --enable-wmaker option compile time option did very little.
In particular, it used a config file in ~/GNUstep/Defaults and it printed
a warning message when users used large icon files.
We now use the ~/.fookb config file in all instances and always print the
warning message.
