Implement Matrix v1.13 changes

[zecakeh]

Here is the v1.13 changelog to follow our progress.

To be sure we don't miss anything, ALL entries of the changelog (except the section about internal changes) should appear here in the same order and category. The ones that we have to implement should be linked to an issue and/or a PR or commit in this repository. If an extra step is necessary when the version is released (like moving it from an unstable feature flag), a subtask should be created. The ones that don't impact us should be struck. The "contributed by"s should be removed to avoid pinging users.
