Title: Enh/spmmcr env config

This patches add support for enforcing and configuring the spm MCR standalone
version via environment variables. The respected environment variables are:

- FORCE_SPMMCR: any value, sets `use_mcr` to True
- SPMMCRCMD: command to use when running spm MCR, if `use_mcr` is True

Additionally, this PR contains two small code improvements in separate commits.
I can remove them, if you want me to.
