Add new ExternalAuth mechanism, Hardcoded

This just lets you enter the database by hand in LocalSettings.php, for
testing.  Now other people can actually test ExternalAuth without having
a vBulletin license.  23 lines not counting whitespace/comments/closing
braces, and took me ~20 minutes to write.

+/**
+ * This class supports external authentication from a literal array dumped in
+ * LocalSettings.php.  It's mostly useful for testing.  Example configuration:
+ *
+ *   $wgExternalAuthType = 'Hardcoded';
+ *   $wgExternalAuthConf = array(
+ *       'Bob Smith' => array(
+ *           'password' => 'literal string',
+ *           'emailaddress' => 'bob@example.com',
+ *       ),
+ *   );
+ *
+ * Multiple names may be provided.  The keys of the inner arrays can be either
+ * 'password', or the name of any preference.
