Enable multibyte character encodings at configure time, with default to

off. Add a resource file to document how it can be enabled. Add a message
to point at the resource file.

Unfortunately the same method does not work for greek keyboard support,
as the resource handling for this is documented but not implemented in
this rxvt version.

Fixes PR pkg/13273, as good as we can for this rxvt version.

+The rxvt binary is able to use greek keyboard extensions and
+multibyte character encodings. Due to errors in the current
+version, the greek keyboard support is not compiled into the
+binary (it can not be disabled at runtime and causes problems
+for users in other locales).
+
+The multibyte character encoding support is compiled in, but
+by default disabled. To enable it, please edit the file 
+${X11BASE}/lib/X11/app-defaults/Rxvt.
