When there's a one line (emote or non-message) event with its avatar
shown and combinable events follow it, that first event delegate's height
is supposed to be one line with the avatar overflowing into
the following event's blank space.
This behavior hasn't been working for a long time. This commit restores
it, along with improving the related code's quality.
- Remove pointless confusing aliases for avatar properties
(smallAvatar, collapseAvatar, etc)
- Make some EventDelegate properties readonly as they should be
- Use Layout.preferredWidth/Height for avatarWrapper instead of both
minimum and maximum W/H
- Make the code cleaner and more declarative
- Start loading past events when the join state of the room changes,
e.g. when accepting an invite, load history right then
- Properly cancel the loading task when leaving the room chat page
Send a pseudo-reply consisting of two messages: a `m.text` which is just
a reply with an empty body, then the file event itself.
This is a workaround to the restriction imposed by the Matrix API,
which prevents us from simply attaching a reply to a media event:

These cause problems with the composer alias parsing code.
If an alias from the config file has whitespace, only the first word
will be taken into account (ignoring any leading or trailing whitespace).
Simplify the code, make it more declarative, and improve the reliability
of sending typing notifications (notably when changing the used alias in
the middle of a message).
If the chat was opened under e.g. "@user1:example.org", but the
composer text is "o abc" where "o" is a composer alias for
"@other_account:example.org", save the composer text to state.json as
"@user1:example.org" and not the alias user.
thumbnail() and download() were remaining.
Use a direct and carefully chosen MatrixClient's methods instead to
avoid problems mentioned in the previous commit 7502c1.
If the display name of a user is blank (e.g. just a space character),
autocomplete it as a user ID.
If the display name starts or ends with whitespace, trim it.
Making the window narrow enough to switch to "mobile mode", then big
again would trigger a signal in SettingsView that switched focus to it,
even when it wasn't visible.
This required us to set the media downloaded local path on events
entirely from python instead of simply lazy-fetching them when needed
from QML, due to pyotherside's async nature and files that must be open
in a certain order.
