Pornotracker v1.3

As the topic says, less than two weeks after the release of v1.2 here’s Pornotracker v1.3. Most of the changes are detailed in this post. In addition, NSF timing was modified to 100% cycle perfect, meaning each sample write falls on exactly the cycle it’s supposed to be on (there was some minor drifting in the previous versions). There are some other changes as well, see the change log for those.
