* Send read receipts
* Add changelog
* Add tests.
* Optimise how sending read receipts work in the timeline.
* Move the check for send read receipts to the presenter
Also improve the way we find the first visible `Event` if we have `Virtual` ones in the timeline.
- `syncUpdateFlow` becomes a `val` and always returns the same instance of the underlying `StateFlow` instead of different `Flow` instances to allow consumers not to remember the `Flow` and not to specify an unneeded initial value.
- `timeline` becomes a `val` as it already always returns the same instance.
- Amends calling code accordingly
- Removes a few unneeded `val`s in `RustMatrixClient
- Fixes a small bug in `MessagesPresenter` that allowed to sometime show a newly created room's name as "Empty room" (changes `LaunchedEffect(syncUpdateFlow)` to `LaunchedEffect(syncUpdateFlow.value)`)
If you are looking at a DM where the other party has left then
when you focus the composer for the first time we'll show a
dialog asking if you want to reinvite the other party.
Closes#590
* Link Compound's `TypographyTokens` to `ElementTheme`.
Also add some docs about when we should use each set of tokens.
* Renamed `LocalColors` to `LocalLegacyColors`.
Made both `LocalLegacyColors` and `LocalCompoundColors` internal. This means it will need to always be used through `ElementTheme.`
Also, removed any usages of `LocalColors.current` accross the project, they're now used through `ElementTheme.legacyColors`.
