Named script messaging

llMessageLinkedScripts(string scriptName, integer int, string str, key id);

Sends a message to all scripts by the name of scriptName in a linked object, regardless of which primitive the scripts exist in.

This would save CPU time in devices where there are a number of scripts that (currently) communicate with link messages, which is often sort of an "Is this for me? No... Is this for me? No... Is this for me? No... Is this for me? Yes!... Is this for me? No..." type of affair.

I guess it would raise a link_message event, unless someone can think of a reason for it to have its own event.
