Rebrand from Piwik to Matomo

Needs to be republished on packagist after merge with the new name, and the old one needs to be marked as Abandoned.

Just a random thought... wondering if it makes sense to have PiwikTracker.php file as well including MatomoTracker.php and then in both PiwikTracker and MatomoTracker class we could have

if (!class_exists(PiwikTRacker)) { . class PiwikTracker extends MatomoTracker }? This way BC works no matter if Piwiktracker file was included or only Matomotracker? Just makes things bit easier even for us as we use PiwikTracker in various places and be great if we give people an easy way to update... otherwise everyone needs to check which file exists and while file should be loaded etc

In Matomo 5 we could then remove PiwikTracker completely (or leave it there if it doesn't cause us any issues)
