Prefer RCRC environment variable over ~/.rcrc

* Centralize configuration loading in rcm.sh(.in)
* Check for readability, not just existence

Add RCRC notes to all manpages. Putting the environment variables in a
table lines them up more neatly and definitively, across all output
formats, and also follows the examples used by e.g. BSD ls(1).
