This patch makes wnb use man(1) to access its own man-pages instead
of relying on textual copies of them being in the $resourcedir.

Similarly, it looks for the compiled-in license instead of opening
its textual copy.

These leave wn.xbm as the only "resource" file, thus removing the need
for a separate resource directory. FreeBSD port installs all -- the
dictionaries and the bitmap into ${PREFIX}/share/WordNet.
