Log Message:
-----------
fixed vertex weight handling of more than 3 bone weights, that milkshape cannot support.
indirect part of the reported issue:
http://www.blender.org/forum/viewtopic.php?t=26251
now, vertex weights will sorted according the weight. in case of more than 3 weights, less important ones will be skipped on export.
