[Saylinks] Convert all GM Command Saylinks to Silent Saylinks. (#2373)

* [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.
