Support personal messages

How should this be implemented GUI-wise?

I guess double clicking a username should add it to the channel list on the left and open a new chat.
Closing could be done by using the remove button in the inline toolbar.

Any other suggestions?

I think that double clicking or receiving a personal message should add a new "Channel list" called "Messages" and below that a list of the users who are interacting with us.

Additionally, a context menu entry in the user list could be added

Please see https://blueprints.launchpad.net/cable/+spec/channels-pms for a blueprint.

For something like thi,s we have to rethink how to represent a list entry in Cable.

Just some help on how to implement this properly.

We should share as much code between normal channels and private chats. We need to create a base class for them (e.g. Chat, Conversation...) and derive Channel and PrivateChat from that base class. All shared code goes into the base class (obviously).

This has to be done in /src/Controller, /src/View, and /src/Widgets.

I'll have a look at this when I'm back to make sure we don't have unnecessary redundancy or bad OOP design in the code.

See the related blueprint for a more detailed spec. Comments are welcome.
