Jeija 194155fff8 Rewrite mesecon wires. This should increase the efficiency and speed of
large machines.

It also makes the wires.lua code easier to understand and more
maintainable. In case any other mod depends on
mesecon:update_autoconnect, please update it to use
mesecon.update_autoconnect. This should also fix some other minor bugs.
Please report bugs if this commit creates new ones.

This commit changes wire looks and removes some unneccesary textures.
