* vNEXT
** Break up 'sourcezap-install' into multiple files
'libexec/sourcezap/utils/install/' contains files that cover both
a fresh install and applying an update
** Add 'setup/setup-doas' improvements
More likely to do what's expected, but blind spots still exist
** Add 'sourcezap setup', 'sourcezap teardown'
Replaces and enhances 'setup-sourcezap'
** Add libexec/sourcezap/commands/sourcezap-sh
Runs /bin/sh within /home/_sourcezap/src/ as the '_sourcezap' user
** Add 'libexec/sourcezap/commands/sourcezap-sh'
Runs '/bin/sh' within '/home/_sourcezap/src/' as the '_sourcezap' user
* v1.0.0
