This menu providers a few text editing related functions, like undo/redo, copy, paste, etc.
As far as I can tell, it never worked in a useful way, though: It operates on the activeFocusItem,
but as soon as one clicks on the menu, this becomes null. It is somewhat useable through shortcuts,
but the text fields have these shortcuts natively.
This is way more useful for sharing, as you can use this link in and
outside Matrix rooms. It also matches behavior with other clients like
Element Web.
I also cut some places where this shows unnecessarily, such as direct
chats and invite-only private rooms.
This happens semi-frequently to me and others - we reply to a user who
has left the room. Sometimes this is useful (for example, bringing up a
previous topic) but in most cases this is accidental, and almost
guaranteed to happen if you turned off join/leave events.
So I added a reminder when replying - which manifests as a small label
in the chatbar - that the user has left and can't be notified of your
reply.
Users generally expect search results to start appearing with the first
character typed; we shouldn't be setting minimum letter counts without
a very good reason. Excessive minimum letter counts are also bad
specifically for Chinese, which is highly information-dense.
Get rid of the minimum letter count.

Update `ChatDocumentHandler` so `RoomManger` is no longer required for saving the text in the chatbar between room switches. This is achieved by allowing `ChatDocumentHandler` to get the correct `ChatBarChache` itself rather than having to have it passed from `ChatBar.qml`. This avoids any race conditions.
Separate out a base `MessageContentModel` that can be extended to get the component types from different places. This is used currently for `EventMessageContentModel` but will be used later as part of the rich chat bar.
All display text is now in the text component so it never needs special casing. This also cleans up some of the model parameters so more things come from attributes including location and file data (which was already a qvariantmap anyway).
Also cleaned up the itinerary and file enhancement views,
