[GMS] Security Update: 0.69

Again, the section is "update", so it is a patch. They did the same for the bug-fix patch. Its name was Unscheduled Server Update, but it was patch 0.68. This time, the name is Security Update, but as the Unscheduled Server Update and all the other patches, it is listed under the "update" category, so it is a patch. Patch 0.69.

EDIT: Also, they obviously need to patch to "implement a new security tool" (in this case, HackShield) in the game.
