Added functionality to show first five messages in statistics view

[cathyxfeiyang]

Description

I added functionality to show first five messages in a conversation (as requested by original repo maintainer). After the user clicks on a conversation to open its statistics popup, there is a listbox showing the first five messages in that conversation with their respective senders. I'm hoping that this can help users easily look back on how their conversations started with friends.

Fixes #29

Type of change

Please delete options that are not relevant.

• Bug fix (non-breaking change which fixes an issue):

• Changed logic of opening Statistics popup: in the unchanged version, opening the statistics popup for a conversation sometimes ran into bugs of "no conversation selected," since the popup was bound to a double click action. I changed this so a conversation is set to current_conversation on click, and the statistics popup opens with this selection.

• New feature (non-breaking change which adds functionality)

• Added functionality in statistics view to show the first five messages in the conversation.
