new port: zgv: a simple/leightweight image viewer + browser that uses svgalib

Note: image browsing is currently broken (floating point exception).
However, you can list images to view on the command line, than viewing works.

+gv is a picture viewer with a thumbnail-based file selector, for the Linux 
+and FreeBSD console (it uses svgalib). It\'s pretty featureful, and is 
+probably the best svgalib-based viewer.
