Just two minor fixes:
1. Font color is black in dark theme. It is now only black for pings.
2. If a user is called `abc`, you can ping them by `@abc_`. Now a ping only takes effect when there are spaces around it.
Based on the `roles` payload in the JWT, the rooms will now give mod permission to Citra Community Moderators. To notify the client of its permissions, a new response, IdJoinSuccessAsMod is added, and there's now a new RoomMember::State called Moderator.
The user would be notified if the message contains "@" followed by the user's nickname or forum username. An alert would be shown, and the icon and message in the status bar would be changed. All notification is only shown if the chat window currently does not have focus.
Also added a connected_notification icon for showing in the status bar.
To allow for passing moderation errors around without impacting the State, this commit also separates the previous State enum into two enums: State, and Error. The State enum now only contains generic states like disconnected or connected, and the Error enum describes the specific error happened.
citra_qt/multiplayer/{state, message} is changed accordingly.
Displayed username along with nickname (when they are not identical); Requested and displayed user's avatar; Made the dialog bigger for extended names.
Added a few functions to web_backend (GetImage, GetPlain) to support getting data in multiple content-types.
Added a no_avatar icon for users without avatars.
* Fix the issue that icons for owned games do not appear
* Fix the issue where you would double click on a room and connect to another
* Fix the issue that room name and nickname does not have size limitation
In dark theme, it is very hard to see the connected/disconnected icons because they are dark too. So I added two white-coloured icons for the dark theme. This also fixed an issue where theme update does not change the icon on the status bar.
* Move Joining state change sooner in the code to prevent an issue where
failing to connect multiple times in a row doesn't change the state (as
it goes from CouldNotConnect -> CouldNotConnect which doesn't trigger a
state changed callback)
* Prevent double clicking too fast on a room in the lobby from causing
issues
* Lobby no longer closes when joining a room
Each window can still watch for state changes to update the ui or to
close the window as appropriate, but for any error announcements, they
all belong in Multiplayer state now.
