wmaker: make the '--replace' de-activable at compile time

Browse Source 
As it is really unlikely that in normal use case someone would need this
feature, it is now conditional code, which is not enabled by default; the
configure scripts now propose a '--enable-wmreplace' option to enable the
corresponding code, as people making package for distributions may want to
enable the feature to provide users the ability to give a try of all the
window managers.
