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.
Having a HoverHandler covering the root ApplicationWindow causes
problems for some Qt Quick Controls with pen/touch, e.g. it's impossible
to focus a TextArea/TextField.
The HoverHandler is moved to HToolTip (since it's used for those),
targets the ApplicationWindow but is now only enabled while a tooltip is
visible.
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.
`preeditText` is partial input from IME and touchscreen
autocompleting keyboards, consider it together with `text` for the
`getWordAt()` function.
This should allow user autocompletion to work properly in these
specific conditions.
Bug introduced in 6b907, made the cursor stay as a normal arrow when
hovering text fields/areas inside a HFlickable due to the
HKineticScrollingDisabler's width/height being incorrectly set.
Previously, member events in initial syncs (unless user had "hide member
events" and "hide profile events" set to false in their config) were
completely discarded with the help of a sync filter, instead of simply
being hidden like events loaded from room backfilling.
This was done due to the common case of rooms getting only
userconfig-ignored/hidden events on startup (especially with the
low number of initial events requested for lazy initial sync),
and thus having nothing to show as "last message" in
the room list (room delegate subtitles).
Other problems resulted from this, like missing join/leave events
when the config was set to hide profile events but not other
member events, and the "Members not synced" (#54) in encrypted room
with recent discarded member events.
The discarding filter is no longer used. Instead, if a room in the room
list has no visible "last message" and is currently visible to the user,
messages will be lazily fetched until we find something adequate or the
room goes out of view.
Contact the server's .well-known API before anything to get
available login flows instead of blindly assuming it will be
m.login.password, and to get the server's real URL instead of
requiring users to remember that e.g. it's "chat.privacytools.io"
and not just "privacytools.io" despite user IDs making it look like so.
The server field will also now remember the last accepted URL.
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.
