Partner price locks and clearer colour names

Features

• Partner price locks: A partner price lock now applies by itself when you create a team, with no code to paste

Improvements

• Colour names: Colours read correctly in more languages, and fall back sensibly when a name is missing
• Pose selector: Removed, because it added a choice without improving results

Fixes

• Tutorial video: The tutorial plays again after the old embed went dead

Security

• Dependency patches: Ten known vulnerabilities closed in the libraries we use
• Privacy policy: Updated our GDPR contact addresses and our UK representative
