Removed rest of common pipe references.

[#27] Code is now entirely free from the common pipe. We can begin
implementing its replacement.

-### The Common Pipe

-The common pipe is a mechanism through which different SALIS simulations can

-communicate. This is done via a FIFO file object that gets instantiated

-whenever a Salis simulation is running. Organisms can push or pull instructions

-to/from this common pipe via the SEND/RCVE instructions.

+### The Common Sender and Receiver

+Common sender and receiver are special functors through which SALIS simulations

+can communicate. Organisms can push or pull instructions via these functions,

+which must be provided by the wrapper application. With some configuration,

+genetic data may easily travel through a local or wide area network.

 ### New features on Salis-2.0

 - Tierran templates are now used instead of keys/lock pairs

 - The instruction set is shorter

-- Organisms can send/receive instructions to/from a common pipe

+- Organisms can send/receive instructions through the network

 

 ### Python integration

 - Salis controller/viewer is now written in python 3
