Update to nabud-1.2.  Uptream change log:

### nabud-1.2
* Added command history to nabuctl on systems that have the BSD
  _libedit_ library and on other systems that have a compatible
  library.
* Added a Baud configuration property to Connection objects.  This allows
  users who have modified their NABU to use a different HCCA baud rate
  clock to specify the baud rate to use.
* Renamed the FileRoot property on Connection objects to StorageArea,
  as the old name could be confusing.  The old name is still accepted for
  compatibility with existing configuration files.
* Changed nabud's -d flag to enable debugging on specific subsystems,
  reducing the amount of logs you have to sift through when trying to
  figure out a problem.
* Added "show all channels" and "show all connections" \ 
commands to
  nabuctl, which shows the details for all channels and connections,
  respectively, rather than just one at a time.
* Added a systemd extra for Linux, along with some other Linux-specific
  instructions, provided by sampson on Discord.
* Added Docker support, provided by Christopher Masto.

### nabud-1.1.1
* Fix an issue reported by jefferystone on Discord -- if you selected a
  file on a "Listener" connection using nabuctl, it would not be properly
  inherited when the real TCP connection came in from an emulator.
* Fix some typos / spelling errors in the document you're reading now.
  Patch provided by cml37.  Thanks!
