Refactor diffs

This refactoring done on top of Marin improvements to side-by-side diff.
Main target of this refactoring is to reduce mess and increase test coverage.

1. Use objects:
  * Gitlab::Diff::Line for line change in diff
  * Gitlab::Diff::File for file changes (diff + blob info)
2. Avoid `yield` magic
3. Move logic from views/helper to models/libs
4. Move diff views under separate dir `app/views/projects/diffs`
