Small kjs value reference patch

[Zack Rusin]

Ave,

increment reference count on the copying object before dereferencing the 
currently held value. It's more for the semantic than technical 
correctness as to invoke a bug a collector would have to be invoked at 
the same time as the copying value is getting out of scope and the 
oprator= with it is called. Possible only in a multithreaded app with a 
funky synchronization, but in any way it doesn't uglify the code and 
seems more natural for people who are used to exceptions. Problems?
