#4 Adding extra margins

[Shaohua Li]

I found Briss is a bit too aggressive when determining the cropped margins. Almost all margins are removed, and this may cause some words at the edges be printed outside the printable area of the paper. I fixed it by adding extra margins when determining the cropped margins at findPosition() in CropFinder.java.
The extra margin is controlled by a variable extra_margin set to 20. You could add a command argument for it :-)
Hope it helps.
