Subject: [PATCH] If the site options are set in such a way that only sysops
 (or only developers) can create new accounts, currently the only way for them
 to do that is to go to Special:Userlogin manually.  This patch adds a link to
 that page on Special:Specialpages, but only if the options are set in this
 way.
