MaintenanceMode

Started MaintenanceMode plugin development, features include:

• Set custom message for when players try to logon.
• Can change the message so it suits the situation and day of maintenance.
• Kicks all players except admins listed in the config when MaintenanceMode is enabled.
• Can be used on both whitelisted and non-whitelisted servers.

Added New Commands:

• /mm adminadd <player> - adds player to admin list.
• /mm adminremove <player> - removes player from admin list.
• /mm kickmsg <string> - Sets the message shown when a player is kicked.

Updated /mm help command

Commands can now be used in console :)
