Improve PHP Install

[zdavis]

We should ensure that zlib, bzlib, tidy-html, libiconv, readline, and libedit are installed in https://github.com/castiron/homebrew-bootstrap/blob/master/cmd/brew-bootstrap-project-all.

We should add a configure command in the brew-bootstrap-project-php file for sane PHP installation. This worked for me on clean catalina:

CONFIGURE_OPTS="--with-zlib-dir=$(brew --prefix zlib) --with-bz2=$(brew --prefix bzip2) --with-readline=$(brew --prefix readline) --with-libedit=$(brew --prefix libedit) --with-iconv=$(brew --prefix libiconv) --with-tidy=$(brew --prefix tidy-html5)" phpenv install 7.2.24

Our scripts are bash scripts, but new macs use zsh. We probably should standardize on one shell. For the time being, we probably need people to maintain a ~/.zshrc and a ~/.bash_profile that have path set and init nodenv, phpenv, rbenv, etc. If nothing else, let's think about how to address this.
