Two new settings that control the use of `SETIDENT` and `SETNAME`: * [set::allow-setident](https://www.unrealircd.org/docs/Set_block#set::allow-setident) now defaults to 'no'. Previously all users were allowed to change their ident (taking into account [set::allow-userhost-change](https://www.unrealircd.org/docs/Set_block#set::allow-userhost-change) restrictions). * [set::allow-setname])(https://www.unrealircd.org/docs/Set_block#set::allow-setname) has a default of 'yes' which matches older UnrealIRCd versions (no change). Perhaps some admins who use controlled (web)chats may want to set this to 'no' if users are not supposed to change their realname/gecos. This is probably rare, but they have the option now.
