[SWFObject] restricting cleanupSWF to SWF only

[Geoff Stearns]

this is interesting... the classid seems like a quick solution...

another one might be to insert a custom class name into each object  
tag and then check for the class name before removing it.

I think the check for classid might be smaller size, though, so maybe  
i'll add this into the 2.0 code and do some tests.

anyone from adobe want to chime in on the classid ever changing in  
the future? seems like it wouldn't be a very good idea, but i know  
that windows media player changed their classid when they went from  
v6.4 to the next one up...

not really sure why though.
