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.
Title this adds a number of options for when messages should be automatically marked as read for the user to choose from.

Remove any dependencies on App from the spaces module. This requires moving some dialogs either to spaces, or libneochat if they're used more generically.
Create a new module for the room info drawer QML. This also requires moving some QML to LibNeoChat common with other modules. Finally all QML in roominfo is modifed to not depend on app.
To make this work `AccountManager` is split off from controller taking all the code around `AccountRegister` and is added to LibNeoChat as it makes sense to have this functionality there.
Make `DelegateSizeHelper` take a `QQuickItem` rather than a width value and move `TimelineDelegate` to use it rather than duplicting the code.
This requires the creation of `LibNeoChat` so that both the main and timeline modules can get access to the class.
Note: ideally more stuff will go into `LibNeoChat` but it turns out our dependencies are kinda spaghetti like and so will take some untangling.
