Created Check Commands

Check bans, mutes, ips, and warns
Fixed SNAdminAPI

If a player is already banned/muted, banning them again on top of that
will overwrite the old values now.
Muting now uses a single method similar to bans.
Bans now require an IP to prevent Null values
Added new Messages to config.yml

Check commands and unbans/unmutes
Created IPInfo Object

Makes checking for null values much easier.
Updated StringUtils

Created a Regex Pattern checker for IP's.  (Used for /checkip)
Updated to 0.9.8-RC1

Release Candidate 1.
Contains all required commands. Error checking now. A new IP banning
mechanism may be created in the final release.
