[Swftools-common] stop tag in wav2swf

[Hartwig, Thomas]

For using the FlashsoundAPI at http://www.flashsoundapi.com I needed the 
stop tag in the end of the SWF file. This is very useful because you 
don't have to load every sound at page loading, but you can then use the 
function loadMovieNum(url,layerNumber), this function always loops by 
default, so there is a stop tag needed.

I have patched the beautiful wav2swf to insert a STOP frame in the end. 
However this is a dirty hack since I don't understand much of the SWF 
structure. I attach this to this email, just use or trash it ;-)

Regards
Thomas
