Remove all scripts from a linkset

This simple script removes all scripts contained in a linkset. I had found one on the Internet but for an unknown reason, it moves the linkset ?! This one is simple, and works for attachments and rezzed objects. Just drop the script in the linkset (so in the root prim). If the linkset is one single prim, there is nothing else to do. Otherwise, when the script tells you that it is ready, unrez/re-rez the object and set all scripts to running using the menu of the viewer. That's all. An hovertext shows the remaining script to be cleaned up. This script is very useful for example for Firestorm's users: indeed when this page is being written down, the feature is still missing in Firestorm.
