Drop console support for 'all' keyword for global permissions, fix typo

* `riak_core_console` supported the concept of granting/revoking all permissions, but `riak_core_security` does not implement it, resulting in ugly RPC errors. Dropped. Thanks @metadave for the discovery.
* In an affront to humanity I misspelled "Successfully" in my last PR. Fix.
