+Subject: [PATCH] Merge "Settings" menu category into "System"
+
+This category is a bit of an odd duck. On a default install, it contains
+only one item: System Settings. Random other apps you install will also
+appear there, but all of these could just as logically live in the
+"System" category. Let's put them there, so as to consolidate two
+nebulous overlapping categories into one clear and obvious one.
