Improve data location

[NoelDeMartin]

In the current version, the movies container will be created under /movies if users don't have a movies contaione declared in their type index. I'm not sure if there's a standard way of doing it, but there have been conversations mentioning that /app/data/movies would be a better default.

Feel free to add any comments/suggestions about this, I probably won't change it at least until I'm finished with the app I'm working on.

I have been exploring letting advanced users choose the location, so I'll probably do that as well. But defaults are still important, given that most users won't bother changing them.

I like this idea!! It would make the root directory of the pod cleaner for the user :D
