Reverting r25772 for now.
The local language names as title are a cute feature, but a few problems:
* It only seems to use the values for the content language for this, though UI language would be more appropriate.
* A hojillion wfMsg() calls are made when Names.php is loaded, which feels kind of icky to me. Would trigger message cache initialization early and does a lot of extra calls not needed 99% of the time.
I'd rather only load values when required.
