Enhance MessagePill

[mjmare]

Some suggestions for MessagePill:

• make the visible property accessible in the IDE
• make it optionally closable by the user
• make it close after some configurable time
• make it "stackable", ie if additional "calls" to message pill would show stacked instances of MP.

Not really. I don't think I should inflict my programming skills on others. It was just meant as suggestions.
