Just loading that plugin already triggers an HTTP request, so lets only
do that when really needed and even more importantly, not for every single
location delegate again.
Always use `NeoChatRoom::getUser` for getting user details in a room context.
- `MessageEventModel` now calls `getUser`
- `getUser` is now overloaded to also be able to take a `NeoChatUser*`
- add params to `getUser` that are needed for the model outputs
- Update the message event and user models so that the full source url is output.
- Separate the reply author into its own role
- Create an empty user object that can be passed so that the QML code no longer needs to check if certain parameters exist.
- Make avatarForMember return and empty QUrl if a valid avatar cannot be found and make use in the user and event models
As well as cleaning up the QML this should also stop the QML Image: Media id '' doesn't follow server/mediaId pattern spam in the log.
Update the message role to be named plainText and use it the message delegate for openMessageContext.
This removes the need for plainText in controller so it is removed.
Change location marker to GPS icon, make sure the point is the anchor and colour it with highlight colour
