YouTrack 5 agile board dark theme

I wanted a dark theme for Youtrack's Agile board. JetBrains added new Darcula theme, but that theme didn't impressed me :(

So, I started to modify theme with Chrome Stylish:

1. Install Stylish
2. Set Darcula theme in your agile board settings
3. Add new style to Stylish
4. Copy style in Stylish from this gist:
5. Set url startswith: http://yourdomain.com/rest/agile/
6. Save style
