modified RC-RegExp after API-Output changed

The order of the properties in a rc-line of the API-Output changed from ... "rcid", "pageid", "revid", "old_revid" ... to ... "pageid", "revid", "old_revid", "rcid" ... thus failing on the RegExp and the matching groups.
(this was probably caused by https://gerrit.wikimedia.org/r/107389 )

So this change modifies the RC-RegExp and the matching group-numbers.

Also I changed NewBlock.Admin, NewDelete.Admin and NewProtection.Admin value from matching group "old_revid" to "user" (if I counted correctly)
