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 Nendo file format.
Nendo is (was) a commercial polygon modeler that has about half of the
features found in Wings. The .ndo file format is a simple, uncompressed,
memory dump of structures that represent the mesh objects, uv coords,
and image textures.
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>
Blender & Wings can read/write ndo files with a maximum of 65,535 edges.
Nendo can read/write ndo files with a maximum of 32,767 edges.<br>
If you have a very large mesh that you want to import into nendo, modify
the 'write_edge_table' function to use a signed integer (i.e., ">h") for the 'len(edge_table)'
field.
