Bug fixes, improvements, and removals (FS-192) (#46)

* Three fixes

* Fixes /tempban throwing a NullPointerException when trying to get a player who isn't on the server but was in the past
* Fixes /tempban banning players for 24 hours regardless of the duration defined
* Fixes /list -t throwing a NullPointerException when performed from a non-player source (such as Telnet)

* Removes hubworld entriely

* Configurable blacklists for tag, muted commands, and wildcard

Changes:
* Moves globally blocked commands to the `global` subsection of the original `blocked_commands` section. You *will* need to update your configurations
* /wildcard's command blacklist is now configurable under the `wildcard` section in `blocked_commands`.
* The commands muted players can't use are now configurable under the `muted` section in `blocked_commands`.
* Removes some commented-out globally blocked command entries.
