BABEL REVIEW /trunk/extensions/Babel @ r88357

Most important issues:
 * 1) It looks like the first parameter of each template invocation is lost
 * 2) CSS should be loaded
 * 3) Possible oldid-induced bug due to wrong use of Article constructor
 * 4) No validity check for category creator user name

General:

Babel.class.php:
 * Babel::Render
 * (1) $templateParameter[0] is unused. Did you mean $templateParameters (plural)?
 * Looks like you did; right now the first parameter is overwritten with the template name
 * Babel::mReplaceCategoryVariables
 * Use strtr. Much easier and guards against double substitution bugs

Babel.css:
 * (2) Why don't you just load this file (with ResourceLoader of course)?
 * Local sysops can put overrides in MediaWiki:Common.css if they want to
 * ResourceLoader automatically flips rules on RTL wikis

BabelAutoCreate.class.php:
 * BabelAutoCreate::create
 * (3) Use new Article( $title, 0 ) instead of new Article( $title )
 * BabelAutoCreate::user
 * (4) Why is false being passed to User::newFromName to suppress the validity check? It seems to me that a user name you're about to create should be valid
