UI Improvements

[Doom032]

• [ ] The width of the friends list should be adjustable so you can see more of someone's name and status
• [ ] If you hover over a friend you should see his name and status in full in a tooltip-like thing
• [ ] Groupchat peers should have their own list on the right of the chat instead of being a big text at the top
• [ ] A confirmation box should come up before deleting a friend (and before clearing his history?)
• [ ] The friend context menu should include an option for inviting the friend to a group
• [ ] The group context menu should include an option for inviting the friend to a group
• [ ] Textboxes should lose focus when the window is unfocused and gain focus when the window gets focused (if they were focused before).
• [x] The send button should be added to groupchats
• [x] The screenshot button should have a clearer icon (photo camera?)
• [x] The 'remove' option should be the last one in the friend context menu
• [x] The send button should use a speech bubble instead of a plus
• [x] The group context menu should include an option to set the group title

Just a large amount of small ideas. Discussion is welcome.
