Merge tag 'v0.1.2' into develop

Looks like it works
Fix: Show default subject for topics without subject
Remember ip addresses (Topic, Comment)
Reject comments/topics from banned IPs
Replies processed by views, less javascript
Pretty urls with friendly_id and skipping /board/ before board name
404 page (static, no layouts, no assets)
Board name and description from Settings.yml
SEO meta-tags, robots.txt, humans.txt, pretty title
Pretty settings
SEO meta-tags and OpenGraph tags (using metamagic)
Post author, subject and text length limits
Create and edit bans in admin page
Some files become little cleaner
