#26 Simplify command interface

[gionnico]

How about popping up a window if you right-click an object with its commands?

If object is landed, it can:
- explore
- stop
- takeoff
- buy
- upgrade
- be sold

If not landed it can:
- explore
- stop
- takeoff
- retreat

Select is achieved by left click and rectangular selection.
Goto is achieved by right click.

For the "write", it should be a command like Pause or Detach.
So CTRL+W maybe more appropriate.

Command line can be kept for commodity of expert users, as a shortcut.
