v1.2.0

Added

• Manage Server members can now define the lowest role that can create events
• Event creator/organizer is now displayed in each event message

Changed

• By default, everyone can create events. Manage Server members and event creators are the only ones who can delete events.
• Roster and settings are now group commands. The old command are still there, but now they must
  be prefixed by either roster or settings. For more information, check out the new help message
• Message prompts will now time out after a minute if the bot doesn't get a response
• Previously admin only commands now require the Manage Server permission instead

Fixed

• Nightfall command would be unresponsive if Bungie.net couldn't be reached
• Registering would fail if there were two account names with different capitalization
• Changing your username would result in duplicate entries in the roster
