Fixes a false install/upgrade requirement introduced in 1.7.1 where the add-on could incorrectly fail if the public package did not include a vendor folder.
This is mainly a refactor release of the codebase to bring everything more inline with best practices from the XenForo core when it comes to service files/finders/etc. Mainly only other devs would care about this.
Bug fix:
Fixed an error when editing blog posts with and adding attachments on edit where they would not associate with the blog post or appear on re-edit/blog post view.
