Willian Padovani Germano 4b01aa7aa5 Scripts: 
The orange -> HEAD merge reverted some scripts to older versions. This only
affected the ones that already existed before the orange branch.
Minor issue, easy to fix.

All in all, kudos to kaito, Hos and others for all the hard work in
bringing (coding, merging) all these changes to the main branch.

This script exports meshes to Wings3D file format.
Wings3D is an open source polygon modeler written in Erlang, a
language similar to Lisp. The .wings file format is a binary
representation of erlang terms (lists, tuples, atoms, etc.) and is
compressed with zlib.
Usage:<br>
Select meshes to be exported and run this script from "File->Export" menu.
Supported:<br>
1. Exports meshes only. Hint: use ALT-C to convert non-mesh objects,
and CTRL-ALT-A if you have "dupliverts" objects.<br>
2. Exports Vertex Colors & Radiosity Solutions.
Missing:<br>
Materials and UV Coordinates info will be ignored.
Known issues:<br>
Exports only well-behaved and topologically correct meshes (i.e,
closed meshes, manifolds, meshes imported from wings, etc). The mesh
cannot have duplicate vertices, missing faces (holes), open edges, etc.<br>
PowerUser Hint: In editmode, if CTRL-ALT-SHIFT-M results in a selection,
then your mesh is not a manifold and most likely will not export.
Notes:<br>
Last tested with Wings 3D 0.98.25 & Blender 2.35a.
