[WIP] New "user interaction" dialog

[exodus4d]

There should be a "user interaction" dialog, that shows a overview of all "active" pilots and some additional information and interaction options (IGB).

Use cases:

• "I want to invite all active pilots in my current system to my fleet" ...
• "I dont know thisuser", -> "start convo" and ask him ...
• "I need help!" Send quick invite all active pilots within 5 jumps to my fleet ...

Objective :

• Bundle all pilots information (active pilots on map), and visualize them on.
• Povide some IGB functions ("fleet invite", "start convo", "add contact", ...), or even allow "batch" function calls for multiple pilots at once.
• Implement some nice feature options (e.g. "show me all active Legions", "show me all active pilots from one corporation", ...)

This is done "for now" no more features are planned (IGB is deprecated by CCP)
