add profile delete methods and ui

[chrismclarke]

Overview
Create a button on the user profile page that allows a user to delete their profile

Includes a prompt for user to confirm their password before delete

This is mainly because firebase requires reauth for sensitive actions, however probably a good safeguard to ensure a user can't easily be deleted if using a shared computer and forgetting to log out

On click the user is removed from the auth database and profile marked as deleted in the database (with all personal information removed)

Todo

• delete user avatar if uploaded
• decide how to handle content attributed to them (e.g. how-tos). Currently all content remains, which is probably preferable
• show notification on successful delete (some sort of toast most likely)
• show notification on error (e.g. incorrect pw provided for revalidation
• handle display of a user profile page that has been deleted (user profile still exists, but only with fields _deleted:true

Cool that's a nice GDPR compliant feature ! Thanks for that.
Considering the todo you want to keep going on working on this feature and I'll merge now and we create separated issues for the todos points ?

[chrismclarke]

I'd say merge and track todo items elsewhere (I don't think they're critical). They're listed in the code but could also add to an issue

Cool looks good, but can you create issues for the todo ? You can gather a few together but so we keep track of it (and maybe a contributor can take on the task)
