####Acceptance Criteria:
* Given that a user is on the Contributions tab,
** And they are the editor who made the edit,
** Or they are an organizer of the event,
* They should be able to remove the edit from being associated with the event.
###Design proposal:
add an 'actions' column to the contributions table, where we'll have Remove as an action (represented with `cdxIconTrash`) - participants will only see the remove action for edits that they have made, not edits that others have made:
{F65780207}
if they click on the Remove action, a dialog comes up that asks if they want to remove their edit from the event, informing the user that the edit will not be deleted, but it will be unassociated with the event:
{F65780209}
if they click on "Remove" on the action, they'll get a confirmation/success message informing that their edit was successfully removed from the event:
{F65780211}
