create map preview pictures during spectating

Browse Source 
pressing CTRL+F12 during spectating creates a clean screenshot and saves
it as map preview picture

  modkeypressed

    returns 1, if a CTRL key is pressed and 0, if not

  screenshotpreview [lines]

    creates a screenshot cropped to 4:3 with a given number of lines
    (in the range of 144 to 480, default 240 or last given value)
    and jpeg quality 80

  gotovantagepoint

    now returns 1, if the map actually has a vantage point set
