Prefer $XDG_CACHE_HOME if defined, falling back to $HOME/.cache.
The Mac cache location is not affected by this change.

Now that Python has been renamed it's important that we still output
which Python they are using for debugging purposes e.g.
```
Python: /usr/local/opt/python/libexec/bin/python => /usr/local/Cellar/python/2.7.13_1/Frameworks/Python.framework/Versions/2.7/bin/python2.7
```
- Document ilovezfs as the official lead maintainer of
Homebrew/homebrew-core. This is a role he's been doing unofficially
(and brilliantly) for a while and explicit documentation of power
structures makes it easier for non-Homebrew-maintainers to understand.
- Document the contents of some of Homebrew's subdirectories for people
clicking around in the GitHub UI looking to contribute.
- Remove update bug mention from README. Enough time has passed that we
can remove this disappointment.
We've been doing this in `brew test-bot`, for our CI and for
homebrew/core long enough that this is a reasonable default that
provides more protection to our users of non-homebrew/core taps.
