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.

Run this script from "File->Export" menu. A pop-up will ask whether you
want to export only selected or all relevant objects.
Known issues:<br>
Doesn't handle multiple materials (don't use material indices);<br>
Doesn't handle multiple UV textures on a single mesh (create a mesh
for each texture);<br>
Can't get the texture array associated with material * not the UV ones;
