Purtle is pretty stable, and quite isolated from the rest of the codebase. It already resides in a separate directory. It seems time to move it to a separate git repo, so it can be used independently of Wikibase.

I hereby propose that the Purtle library be made completely independent of MediaWiki, therefore the statements within init.mw.php would be moved into a separate MediaWiki extension called "Purtle" depending on the Purtle library via Composer.
It's not a dependency, just an optional intergration with MediaWiki. I think the only thing this does it to cause extension credits to be shown on Special:Version.
A separate extension just for that would be annoying to manage. I'd rather just kill the code.
