[CM2] WIP continues for rendering2

- Add absolutePath field into fileSystemTree to vastly simplify copying assets
- Add a copy method to renderer for copying assets/files
- Implement copyAssets view
- Delete the legacy localAsset (attachment) view. Copy them as part of
  their parent entry's view
- Remove pagination from homepage. Pagination takes places in collections.
  Collection indexes may be used as homepage (in the future)
- Implement post view as part of collection
- Implement tags and category views as part of collection. And paginate them
- Assume a postsPerPage field in categories and collections.
  Cascade: settings.ppp > collection.ppp > category.ppp
- Render categories, tags and posts as part of collection view
- Add date field to asset just like in attachment
- Fix attachment outputPath (it was assuming it's always in a category)
- Homepage passes a 'homepage' (instead of 'page') context to its attachments,
  so it doesn't count in attachment outputPath
- Delete filterPosts helper. Filtering posts sounds like a template's job
- Init settings in CM2 test so there's some settings.out to work with
- Call move getSettings() call into function runtimes, so settings.out
  is not undefined when testing contentModel2
- Update CM2 test fixtures to include absolutePath in FS nodes
