Resources download functionality

[naruaika]

I guess it's better to have this functionality. This is including downloading pages, translations, tafseers, and recitations. So, instead of put them all in this repository or others, we can make the app to download from the original sources when it's needed.

On the other side, it has made me think of how to re-download them if there's a new release from the upstream. Since not all original download sites features versioning to their files. This is would be specific for the translation and tafseer only.

Please also consider how to apply some pre-processing procedures, for pages is highly pre-processed to obtain all the bounding boxes. Thinking of doing resource-intensive pre-processing on the user side is barely good at all. I'm talking about not putting all the resources on our special repository.

Since we are using translations from Tanzil.net, please read the terms and use. In my understanding, the following quote is clear that we are not allowed to redistribute it to our repositories:

Redistributing the following list in another website is not allowed, unless direct permission is granted by the Tanzil Project.

So, pre-processing on the user side can not be avoided.

By the way, we need to put a link back somewhere (maybe in the about dialog?) to http://tanzil.net/trans/ as we're going to use more than three of their translations.

I was thinking if we want to implement a scrapping to watch the translation log at Tanzil.net to re-download the resource once updated. Is it safe and legal? I won't think if we need to regularly re-download then extract the update at information from it, despite having small sizes (around 1 MB) ...

Is there any good reason to include resource removal functionality?
