Kanban view for emails

[jeremyscatigna]

The goal here would be to create a Kanban type of view but for emails:

• 4 columns by default Backlog, Todo, in progress, Done
• User can update column names and create new ones to match workflow
• At the beginning all emails are in the backlog
• User can drag and drop emails to other columns
• When an email is dropped in an other column it adds the appropriate label to the email (column name)
• When reloads the emails should be in their appropriate columns based on the label added
