1d4d2b0204
This patch is slightly large (I think still within the guidelines tho) , but also pretty straightforward. I thought for a while about how I could split this up in a straightforward way, and I couldn’t come up with anything without breaking intermediate builds. - Deleted a lot of old/unnecessary code (ie. the Collection extension for MuteItem, since we’re now using the MutelistManager sets) - Changed damus_state.contacts to damus_state.mutelist_manager for all mute list manager work - Updated MutelistView to take advantage of new code (this is probably the largest change in this patch) Lighting-Address: fishcharlie@strike.me Signed-off-by: Charlie Fish <contact@charlie.fish> Reviewed-by: William Casarin <jb55@jb55.com> Link: 20240210163650.42884-4-contact@charlie.fish Signed-off-by: William Casarin <jb55@jb55.com>
