Backend for Automatic Micro Blogs
This MR introduces automatic personal blogs to the Blog client. When a contact is added, her personal blog will also be added automatically. Also, when a new identity is added, a personal blog for that identity is created.
The first commit changes the blog paradigm to short-form blogs and introduces other things that will be useful later in the UI (!214 (merged)) such as a BlogPostAdded event and the possibility to delete/remove blogs (not the personal ones).
This MR is based on !224 (merged) to prevent crashes that are fixed by it. So please review and merge !224 (merged) first.
