This commit will bring:
- Linking to other users with `@username`
- Linking to tags with `#tag`
- Opening external links in new tab (Fix#1647)
- Single line breaks to avoid confusion for non-technical users (Fix#1377)
- 😒 support...
- Email encoding in markdown
- Markdown editor now auto-resizes to accomodate content (Fix#1379)
NOTE: This only works in very few places. We need to wait for #1835 to have those features available widely
