Update Riot to 1.5.8
Changelog available here
Attention:
This version contains an upgrade to the cryptography database version. Once users run this version, their session's indexeddb store will be upgraded and older version of Riot will no longer be able to read it. Users will have to log out and log in if the version of Riot is downgraded back to a previous version.
Packaging change: Switched back to tarball now everything works again
