Add remote error logging service with opt-in

[mrfrase3]

Debugging can be a pain, especially if a user is under arcane technical governance. But remote error logging captures a lot of data which, whilst really useful, would conflict with the privacy policy and COPPA compliance. Ideally, this should only need to be turned on by people assisting with debugging issues.

• Choose and create an account with an error tracking service
• Add an opt-in setting, with plenty of warnings around it
• Integrate errors to be caught with service if enabled
