Zkarim: Changed the images to non-zoomed in versions. Changed the Shift Register image to have the wire coming out the side instead of the top.

Zkarim: Added two tables for the tunnel types and appearances for input and output tunnels for for loops. Also, added a third table showing tunnel types for case structures. The tunnel types for inputs included autoindexing and disabled indexing (normal). The tunnel types for outputs included indexing, last value, concatenating, conditional, shift registers, and default if unwired. The tunnel types for case structures included linked input and output.
