Post editing

[ericm]

Registered users should be able to edit their posts. This could be done through a generic post editing component, which would have fields for:

• Title
• Description / Content

or it could be done with unique edit pages for each type of post.

Ideally there would be a public viewable edit history, or at least a marker to flag that a post has been edited. For authentication, Firebase could be used to compare the UID of the poster to the UID of the request to edit.
