spacetime publish/generate --build-options requires a '=' and is undocumented

[jdetter]

This doesn't work:

spacetime publish --build-options'--skip-println-checks' <module-name>

This does work:

spacetime publish --build-options='--skip-println-checks' <module-name>

We should update the help text to make it clear that you need the =

Yeah, I mean = is the only way to clarify that you're passing a value to --build-options rather than as an arg (and --build-options'--skip-println-checks' is the same as --build-options--skip-println-checks which is.. not a valid arg).

I'll update the helptext.
