Update release script to produce production build #185
Description
The release script does not attempt to collect the files needed for production -- this is manual for whomever is shipping to SVN. With the addition of autoloading for some production files, the vendor directory is now required; however, we don't want to ship dev packages.
Need to add a step of the release script to output the files needed for production (composer install --no-dev, exclude phpcs files, etc).
