Internationalization of MapServer - Documentation

[jlacroix]

The internationalization of mapserver is now commited (bug 858), so we need to
update the documentation to reflect those changes.

The mapscript README have been modified to add the new ENCODING parameter in the
label object.

But the mapfile documentation still need to be added. In the LABEL object
there's now an ENCODING parameter. This parameter should be a string. The string
should be a supported encoding format. If the format is not supported, the label
will not be draw. Also the iconv library need to be supported. The library is
always detected if present on the system, but if not, the label will just not be
drawn. Note that on all average system the library will be present.

Also it could be cool to add this document to the official documentation:
http://mapserver.gis.umn.edu/bugs/attachment.cgi?id=183&action=view

The document is attached to bug 858.
