Composer installable patch to get SilverStripe 3 running on PHP7
Installs a patch (basically https://github.com/lekoala/silverstripe-327 and some minor changes by Mark Guinn, see https://github.com/markguinn/silverstripe-framework/tree/patch-3-327) via composer, so you can run SilverStripe 3.2+ on PHP7.
Uses composer plugin https://github.com/netresearch/composer-patches-plugin to install the patch after a
composer require wernerkrauss/silverstripe-3-php7:^0.1.0,
then change your server to run PHP7 and enjoy the speed it provides.
