add a bunch of stuff to make a functional (fake) pipeline
first try at a cors test
replaced pipeline-based solution by env-based one
Add support for sending emails/notifications in env
Add get_keys and remove method caching on buckets
Allow environment reusing
restore bucket method caching adding a values field
Add extra tests for core
add missing inspect in Console
change the way package.path works on helper

This is because not all middlewares have their file equal to their
folder name. For example yo-api -> yo.lua (without the -api). This
allows making require ‘yo-api.yo’
start working in yo
Do not remove string.rep in sandbox
Move inspect from spec/env to spec
remove magic from package.path
remove unused sandbox.lua file
transform helper into expect-based
helper -> expect
Add expect events support
update yo to expect syntax
Merge branch 'update-cors' into middleware-testing
