Things I did:
- remove mainlines resources
- deevad's brush pack
- deevad's first patterns pack
- update the link to Vasco brushes
- the old one doesn't lead to any brush pack
- the new one lead to the old version, unfortunately
- the other option would be to link to someone's deviantart, but that won't do because deviantart doesn't allow downloading for non-users now :( https://www.deviantart.com/grindgod/art/Krita-Modular-Brushset-v5-550590458
- reduce the width of texture pack and the video in tutorials area
