Hide blinking cursor in colorama output

Fixed using ANSI escape codes in posix systems

Windows support should still be added if wanted; take a look at [this link](http://stackoverflow.com/a/10455937) which also describes a solution for windows. Added `if os.name == 'posix'` checks so that the code should still work fine on Windows (displaying a blinking cursor)

As with `curses`, all exceptions should call the `beeindig_sessie()` method so that the communicator can restore things nicely...

Also re-added the info dialog for pinging since it seems not to cause the other crashes, as discussed a moment ago
