[swfmill] do not set name property on as3 swf instances

[Will]

just worth noting, if you are doing something like:

<?xml version="1.0" encoding="iso-8859-1" ?>
<movie width="500" height="400" as3="1" framerate="12" version="9">
  <background color="#cccccc"/>
  <frame>
    <library>
     <clip id="Foo" import="as3class.swf"/>
    </library>  
    <place id="Foo" x="0" y="0" depth="1"/>
    </frame>
</movie>


you can not set the name property for the placed clip. e.g. this breaks:

    <place id="Foo" name="myFoo" x="0" y="0" depth="1"/>
