Move token requringness check to the ApiMain
Adding an exception if we're using "gettoken" (block/unblock)
Remove array( 'missingparam', 'token' ), from the getPossibleErrors of modules that set requireToken method to true
"I wouldn't object to stylizing the API code to bring it in line with
the rest of MW on principle, but I'm not gonna bother myself." --Roan

* Make UserrightsForm::doSaveUserGroups(), addLogEntry() and helpers non-static again so CentralAuth can override them; remove the short-lived UserRightsLogEntry hook
* Let UserrightsForm::fetchUser() return a WikiErrorMsg on failure
* In ApiUserrights, use an instance of the UserrightsPage class rather than calling its methods statically. This also enables interwiki userrights in this module
* Add some messages to ApiBase::$messageMap
