New formula zpython: Zsh Python Module

This formula provides a zsh python module that allows executing python
as a zsh builtin. Its current main purpose is speeding up heavy
prompts like powerline.

It requires at least zsh 5.x.

More info: http://www.zsh.org/mla/workers/2013/msg00089.html

Closes #20182.

+    To use the zpython module in zsh you need to
+    add the following line to your .zshrc:
+
+    module_path=($module_path #{HOMEBREW_PREFIX}/lib/zpython)
+
+    If you want to use this with powerline, make sure you set
+    it early in .zshrc, before your prompt gets initialized.
+
+    After reloading your shell you can test with:
+      zmodload zsh/zpython && zpython 'print "hello world"'
+    EOS
+  end
