wmaker: create script to handle conditional and variables replacement in man pages

Because the man page references some stuff that are dependant on the
configure options, it is a good idea to update the man page accordingly, so
the user will not be puzzled later.

There is now a script which takes care of replacing '@var@' in the same way
autoconf does, but also which can handle conditional '@def@' removal (for
the case of feature dependant command line options).

The man page for Window Maker is now processed this way so user will always
see accurate information.
