Blog MVP

What should work:

• showing unified blog feed when clicking blog icon in sidebar
• showing progress animation while loading
• updating list as new blog posts arrive
• writing own blog posts
• reblogging blog posts

Stuff that is missing, but should probably be added for a not so minimal prototype:

• show when blog post is unread
• show unread bubble in sidebar
• show unread FAB to jump up to unread posts (if any)
• use RSS avatar when post is from RSS feed
