### Added more hidden timeline events with settings and rendering.
([#934](<#934>) by @7w1)

#### Settings

- Added a master Show Hidden Events toggle with per-type sub-toggles for
message edits, redactions, reactions, and other unrecognized events
- Sub-toggles stay visible beneath the master toggle and are disabled
while hidden events are off

#### Timeline rendering

- Show message edits as timeline events with reply navigation and an
inline word/line diff between versions
- Show reactions, message redactions, and reaction redactions as
timeline events
- Keep redacted reactions in the timeline as tombstones with redaction
events linking back to them when possible
- Improve reply-chip previews for edits, redactions, reactions, and
redacted targets

#### Safeguards

- Hide forward, delete, and other message actions on timeline meta
events that cannot be forwarded or meaningfully deleted
- Disallow forwarding deleted messages and other non-message event types

### Add polls! ([#916](<#916>)
by @nushea)

#### Add Polls with a new Menu for adding items

- The polls have a simple style for showing and interfacing with poll
events
- There is now a simple interface for creating polls which integrates
the spec
- Now the Plus button on the bottom left can open a menu for selecting
what to send, which will be useful for future options as well
- For the people that prefer to only add files with that button they can
disable the menu and still create polls with the /poll command
- You can see who voted for what in a clear menu

([#896](<#896>) by @nushea)
* Migrated all icons to Phosphor Icons and added a setting to display
globe/lock icon instead of the hash tag for the room sidebar.
