* [Saylinks] Convert all GM Command Saylinks to Silent Saylinks.
- This cleans up all non-silent GM Command Saylinks that we had before due to the way they worked before. All saylinks like this should be silent now.
- Add source short hand capability for say links with same link as text.
* Defaults to r anyway.
* Spacing.
* [Dialogue] Add support for Dialogue Window titles.
- Custom title allows defaults to be overridden where necessary, like a leaderboard or something.
- Default target to client in case people want to send Dialogue Windows from current client.
* Fix possible issue with markdown.
- Example: Using the word "title" or using any identifier and forgetting the colon.
* Implement auto saylink injection
* Cover Lua say since it takes a different code path
* [Dialogue] Dialogue Window Middleware (#1526)
* Dialogue window quest dialogue work
* Add rest of DialogueWindow hooks
* Remove spacing
* [Dialogue] Add support for Dialogue Window buttons.
- Also changes "mysterious" identifier to "{mysterious}".
- Both button names are required for anything to show up, otherwise it defaults to Yes/No similar to Client::SendFullPopup.
* Move SetEntityVariable so responses can override default button response.
* Add negativeid support so you can override button two popup ID.
* Fix log.
* Update dialogue_window.cpp
Convert button names to strings and negativeid to secondrespondid.
