cmd: add support for long commands

- Long commands are commands that is 2 or more characters,
  and MUST be completed by pressing enter.

- A given command can have a long-command, a short-command
  or both.

- All long commands are using '/' (slash) prefix

- a simple TAB-completion is supported, while punching in
  your long command you can press TAB to see a list of
  commands that matches the input string.

Feedback is welcome, specially on the long-command strings
itself. If you want to suggest changes, please make a small
and non-intrusive patch and send it as a Pull Request (PR).
