Copperbox revision 2615.

I've changed the BoxConnector API so it follows the same instantiation pattern as path connectors (the instantiation is modelled after Parsec's Token module though it is a bit different).

Doing this, I realized box connectors cannot reuse the library of "box" incline trails as the incline trails don't account for spacing (rightfully so). I'll have to write an adaptor function for box connectors to overcome this.
