* Fixes #276 - Rebuilt room timeline: - Removed the need for the ListCollectionViewAdapter - Rewrote the TimelineItemList without using introspection - Added ReversedScrollView for laying out items at the bottom/trailing - Rewrote TimelineProvider diffing through CollectionDifference (similar to the RoomSummaryProvider) - Added back `scrollDismissesKeyboard` behavior - Various other tweaks and fixes - Fixed various warnings: - removed async AttributedStringBuilder as AttributedString is non-sendable, made the RoomTimelineItemFactory synchronous - removed unused virtual timeline items - removed unused isOutgoing property from the FormattedBodyText * Make TimelineItemContextMenuActions indentifiable and specify contextMenu identifiers * Bump the matrix-rust-components-swift to v1.0.16-alpha * Add changes file and changelog contribution guide * Fix attributed string builder unit tests
