User messages screen

[StarlingZen]

As a signed in user i want a screen that shows all active conversations with other users so that I can easily find the conversation I'm looking for

it is acceptable when....

• a screen exists that displays conversations in order of most recent message sent or recieved
• each chat displays an icon with an image of the item being conversed about
• each chat is titled with the name of the item talked about
• each chat has a subheading with the last message either sent or recieved
• unread messages are in bold text
• the user can delete chats
• chats that are related to sold items are automatically deleted 30 days after the item is sold as long as no issue is raised
• the user can return to the user home page
