PHPUnit 10 fails with old configuration schema while older releases only
print a warning.
Stick with at most v9 for now, as we are testing against older PHP
versions that to not support the new scheme.
The build process is trivial and does not require an additional task
runner and deployments are done by the GH action, so we can remove the
Robo dependency and clean up the build environment.
The plugins purpose is to exclude or filter certain requests from
tracking by Statify. However the current name "Statify Blacklist" is not
actually inline with today's understanding of such terms. In WordPress
Core 5.5 the word "blacklist" among others has been replaced by more
precise wording where possible.
The term "filter" has been used in various places already and clearly
describes the behavior of this plugin. So we rename the plugin to
"Statify Filter" and rephrase front-end texts.
Plugin slug (permalink), textdomain and all public class and constant
names left untouched for now, to not introduce breaking changes at this
point. To be cleaned up with next major release.
Created tasks for building and testing using Robo build environment, installed via Composer. This is supposed to replace Gulp as default build tool and makes NPM obsolete.
Bundling a ready to use plugin ZIP has been automated into a Gulp task. After executing unit tests and code sniffer, only the relevant files are bundled.
