UI Enhancements for messaging/chat feature

[stellarmagnet]

• nav issue: you have to click on the message text to open the chat box. instead it should be the rectangle
• chat box: The Name is missing from the title of the chat box
• chat box: close icon should be on the title of the chat box. the close icon should CLOSE the box, not minimize it. To minimize you click on the bar itself (like FB)
• chat box: fix the location of the avatar
• chat box: when a chatbox is open, i shouldn't have to scroll to see new messages
• We should not use "chips" to display the people in a chat. Right now you can remove people from chat by clicking the x next to their name. This should not be enabled. Remove that row. The name of the person you are chatting with should be in title
