Subject: [PATCH] POC: Adding bash-completion to byobu.

* Linking repositories containing the files for future traceability (License: GPLv2)
* Symlinking the required files
* Adding bash-completion to byobu executables:
  * Hard-coding `byobu-tmux` and `byobu-screen` to respected complete-functions
  * Small shim to redirect on the correct bash-completion function
    in case of using the plain `byobu` (as expected on the normal usecase)

Tested under Ubuntu 16.04.3.

_Note that unfortunately, I didn't have screen installed to test or verify the actual
usage of `screen` file. I am not familiar with `screen` commands, but I was seeing
bash functionality "completed". However, autocomplete changed realtime to the
contents of `source`d file._
