Move showMessage to RoomManager and merge warning in. A new Message type enum is created aligned with the Kirgami.MessageType used by Kirigami.Banner to avoid needing to translate from 2 enums.
showMessage is also sent as a signal from NeoChatRoom (and via the room from ActionsModel), this removes the need for them to have a dependency on Controller (and RoomManager). While not necessarily the cause of Windows crashes the spaghetti dependencies of RoomManager and Controller throughout the code base has made debugging that harder so this aims to simplify that as well.

Note: there is still an issue where after starting a new thread the threaded messages only appear after a restart as the root event needs re-downloading from the server to get the thread info added. My plan is to tackle this next.
Add a model for managing permissions (power levels) in rooms. This gets rid of a whole bunch of boiler plate in NeoChat and as a bonus makes it easy to add a feature to allow setting the permission level for any event.
This draws heavily on what @carlschwan did in network/neochat!1579 but I found it easier to start again and grab the bits as I needed them plus some other copying from what I did in the Space tree model.
From my current limited testing this seems to work nicely try and break it.
This adds previews for downloaded pdfs and code files.
Move the itinerary model representation to it's own component and instantiate from MessageComponentModel. This starts to lay some groundwork for previewing other files.
The aim is to be able to use separate delegate for things like codeblocks and quotes so that they can be styled differently.
For now everything should look identical. However this moves to using a model for the content of the message and is intended to lay the foundation for improved message content representation, e.g. splitting up a text message in multiple sections and using different delegates for things like code and quotes.
Similar to text handler, pull out the disparate array of functions which format information from an event ready for display in the UI and put in a handler class with a test suite.
