add unit tests while doing next refactor

[leonstafford]

• use shellcheck

[leonstafford]

allowing args passed to script will make it easier to test (along with the benefit of enhanced functionality)

so, we should be able to do things like

• sh go.sh create mynewsite --php 8
• sh go.sh open mynewsite
• sh go.sh list
• sh go.sh ssh mynewsite

• sh go.sh status mynewsite

  Update: forget this, args being set via vars, like var1=foo sh go.sh. Actions like launching in browser can remain via wizard, no big need to ad-hoc run that

and adjust command to just lokl, so lokl create mynewsite --php 8

Update: forget this, args being set via vars, like var1=foo sh go.sh. Actions like launching in browser can remain via wizard, no big need to ad-hoc run that

unit tests / code coverage progressing nicely now.
