New Transmission add-on thread

I had the permission denied error too at first. It turned out that the folders Transmission was using to put the incomplete/completed files did not have write permissions for the Transmission user (nogroup / nobody). After getting the permissions and folders right, everything works ok with me, though it usually hogs up a lot of memory when it's downloading. I think the standard setting is that it is using a buffer of 2GB i think, which is a bit more than the memory in a Duo...
