mycroft-use should tell you which train you are on

mycroft-use should tell you which train you are on when $0 is null

---

• I'm running a PiCroft
• With version 18.02 of the Mycroft software

• With the standard Wake Word

instead of mycroft-use falling back to mycroft-use --help

root@picroft:/home/pi# mycroft-use 
usage: mycroft-use.sh [stable | unstable | home | home-test | github [<path>]]
Switch between mycroft-core install methods

Options:
  stable           switch to the current debian package
  unstable         switch to the unstable debian package
  github [<path>]  switch to the mycroft-core/dev github repo
<snip>

It would be useful for it return what Train you are currently on! This is ESPECIALLY important for Devs who might have different branches, and the CLI (master) may not reflect what mycroft is running.

So something like:

root@picroft:/home/pi# mycroft-use
- You are running Mycroft Stable (v0.9.14)
- You are running Mycroft Untable (v18.02)
- You are running a git version from repo: /home/bill/projects/mycroft/custom
- You are running a git version from repo: github.com/billsprojects/mycroft-custom
