do not delete temp files

[Perfect-Web]

can you add a new argument that will not delete the /tmp folder so that it can be used on subsequent runs ? for example i wanna sync multiple hosts with the same images, so if i run the script once for each of my hosts, it will dump/delete the archives once for each call which makes it very inefficient. On the other hand if they are kept and just dumped when required it would be alot faster.
