Add operator <- for move semantics and operator <-> for in-place swapping. Essential components to making the unique ownership model work. Steal <- from send, turn operator send into |> and make it chain to the right.

<- is in, but the typestate component doesn't exist yet. Receive is now |> but doesn't chain.

Is there much left to do here, aside from "fix bugs as they occur"?

Tim has implemented the typestate stuff.
Currently we don't properly check that the arguments to swap are lvals and that the RHS of move is a local. The former will trip an llvm assert, the latter will compile and do the wrong thing.

Otherwise I think it should be good?

Heh. Ok. Want to fix those?

The swap issue has been fixed in #590 and the move issue has been opened as #591.

I'm going to close this bug.
