Add run.n and template.zip

It's extremely inconvenient that the dev branch doesn't have a run script. Of course, newcomers are unlikely to run the dev branch right off the bat, but it's still an issue in my opinion. 

I just copied the run.n and the template.zip over from the last release, not sure if something in there needs to be updated.

Adding a FlashDevelop project file should also be considered, it's what most people use for Haxe development from my experience, the fact that the haxepunk template does not contain one is a pain. For people who don't ues FD, still no harm done if that file is there.
