Make nginx more convenient; clean up caveats

No shin, screw that. Make nginx use a sensible docroot. All web servers should use this docroot from now on. I suggest the symlink method to making them do this so it is easy for people to change this on a server-by-server basis and have multiple docroots.
libwebsockets: use git checkout

Rationale: the tarballs are timestamped so the hash changes on every
download.
pngcrush: fix URL

Fixes #19131.
Fix google-app-engine

Add "_python_runtime.py" to the file list.

If this file is omitted then google app engine can't run in development mode and raise the following error:
/usr/bin/python: can't open file '/usr/local/bin/_python_runtime.py': [Errno 2] No such file or directory

Fixes #19143.
versions: work for tapped formulae

brew versions is hardcoded to cd to HOMEBREW_REPOSITORY before running
git, and as such fails to report previous versions for any formulae
from a tapped repository.

Add two new private methods repository and entry_name to replace the
hardcoded HOMEBREW_REPOSITORY and formula path, and brew versions
work for both builtin and tapped formulae.

Closes #12356.
Closes #19069.
