* fixing lint errors
* Changes based on discussion
* Changes based on discussion 2
* Changes based on discussion 3
Yay! More changes.
* Fix for incorrect oldMember in guildMemberUpdate event after addRole
`addRole` would modify the cached GuildMember rather than letting it be handled internally when a guild member update packet is received from Discord, leading to the `oldMember` and `newMember` being identical following a call to `addRole`
This is currently how `addRoles` does it, and a correct oldMember is passed to the `guildMemberUpdate` event following a call to `addRoles`
* Return cloned member with added/removed role
So we can return a member object with the added/removed role without affecting the member object sent to `guildMemberUpdate`
* Wait for guildMemberUpdate and return updated GuildMember
* Fix linter errors
* Remove listeners after 10 seconds
