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.
Create a cpp helper class to calculate the correct delegate width given it's parent width.
This is designed to be more robust and hopefully easier to understand than the current mass of javascript calcs.

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
Restore the functionality to edit or reply to the last message in the `chatbar`.
This is achieved be moving the functions `getLastLocalUserMessageEventId` and `getLatestMessageFromRow` to `NeoChatRoom` as `editLastMessage` and `replyLastMessage` as `chatbar` no longer has access to `messageEventModel`.
The functions are also simplified as they only need to find the `eventId` and always from row 0 as this was the only use of the functions.

Create a reaction model that provides all the required data for `ReactionDelegate` so that none need to be calculated in QML.
This also cleans up the API for `ReactionDelegate`
Limit the maximum number of avatars shown for other user read markers and collapsed state events
For state events \

For read markers \

This move the finding of links and the creation of a `linkpreviewer` into c++.
- The links are now extracted from the text in `texthandler`
- The `messageeventmodel` now creates and stores `linkpreviewers` for events that have links in the current room.
Two new model roles have been created to let a text delegate know when the link preview should be shown (`showLinkPreview`) and pass the link previewer (`linkPreviewer`). Empty link previewer are returned where link don't exist so the qml doesn't have to have checks for whether the parameters are undefined.
Further improvements to the handling of `mediaInfo` in `messageeventmodel`.
`blurhash` and `thumbnailInfo` are now replaced with a single `tempInfo` object that contains a single temp source. The priority is thumbnail > `blurhash` > empty if none exist.
Fixesnetwork/neochat#235
Create a `messageeventmodel` role for media info and reply media info that is a QMap with all the required data.
This replaces the MediaUrlRole, FileMimeTypeRole and the ContentTypeRole. The reply role no longer needs the content role.
This also ensures mxc urls are now generated for replies. All the media parameters will now have default values assigned in the model so the QML no longer needs to do this.
- 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.
