FEATURE: group_removes_trust_level setting

Browse Source 
By default in Discourse, if a group grants a user a particular trust
level that is locked even if they are removed from the group.

With this new setting, when a user is removed from a group their
trust level is set to either the next highest trust level based on group
membership, or they are unlocked and promoted based on the default
mechanisms.
