(bug 27468) Move private styles out to their own section, so they override everything except user styles. Moved from one makeResourceLoaderLink() call with array_merge() to multiple calls, because makeResourceLoaderLink() orders the modules, then groups them, so the input order is not preserved. Also fixed an issue in makeResourceLoaderLink() where the $uery variable was reused in each iteration but not cleared, allowing pollution to occur in theory (doesn't seem to have happened in practice, though).
