Add complementary information to apps descriptor file

@theorenck commented on Thu Jun 07 2018

Based on a discussion with @thiagosanchz about what information we need to have in the app description page, we would like to suggest some improvements:

• [x] description: this one could be a long description limited to just one or two paragraphs long
• [ ] summary: just a brief description, possibly just one line, just about one or two phases long
• [ ] website: If the author want to better "sell" his app idea, he should do this in a page of his own
• [ ] categories: on the Marketplace designs we have the concept of categories, shouldn't them be inside the descriptor file?

Thoughts?

See the discussion on #49. We will be moving to package.json and taking a page out of VSCode Extension manifest file book on how to approach this. However, due to moving away from app.json file as the manifest file, we will have to change the properties and thus this will change the internals of the framework system which is not a small change.

@d-gubert this issue still makes sense?
