[kepler-dev] download actor from "kepler analytical component repository"

[Chad Berkley]

Hi Eric,

I changed the code in kepler to allow you to configure the created 
LSIDs.  There is now a key in the 
configs/ptolemy/configs/kepler/resourceBundle.properties file that will 
allow you to change the lsid authority in all of the lsids that kepler 
creates.  I tried it on a different kepler repository and it worked. 
Let me know if it works for you.
