nfdc / dvc + URI refactor + client conf

[pulsejet]

I/O compatibility with nfdc is a non-goal. This is a debugging tool.

TODO:

• Allow face URI when adding route
• Create face if needed when adding route
• Documentation

Usage: ndnd fw [command]
  run             Start the NDN Forwarding Daemon
                  
  status          Print general status
  face list       Print face table
  face create     Create a face
  face destroy    Destroy a face
  route list      Print RIB routes
  route add       Add a route to the RIB
  route remove    Remove a route from the RIB
  fib list        Print FIB entries
  cs info         Print content store info
  strategy list   Print strategy choices
  strategy set    Set strategy choice
  strategy unset  Unset strategy choice

Done with this - too many things ended up here as usual.

There's documentation in the repo for the new nfdc and dvc tools - I plan to set up a github pages to consolidate it.

This also implements client config and closes #85
