Adding new features to `App.buddylist`

[Marak]

The buddylist for the Alpha is functional, but very simple:

Current features include:

• buddy is connected status green and orange icons
• sort buddies by last connected
• show new messages from buddy speech bubble icon
• show incoming call / on call icon

We'll need more features added to the buddy list to get out of Beta:

• Search buddylist by name
• Ensure buddylist can render up to N buddies ( virtualized shadow DOM )
• Add ability to group buddies ( renameable / one buddy can be in multiple groups )
• Add ability to right-click buddy name and get profile
• Add ability to set Status ( Connected, Away, Custom )
• Add ability to see buddy status icon and text ( small text, hide overflow )
• Add ability to right click and block buddy
• Add ability to right click and remove buddy

Open to community suggestions on this one. Let us know. Will continue to update this Issue as we make progress.
