Release 0.6.1-rc.4

0.6.1's fourth release candidate: the Stats page's range buttons follow
the retention settings, jarl changeset show prints local time, and the CLI
no longer prints "and N more" when the server sends no PTR list.

 ### Changed
 
+- The Statistics page's range buttons follow `stats.retention`: ranges
+  longer than any data kept are left out, and **1y** and **2y** appear
+  when `retention.day` (or `retention.hour`) covers them (with the
+  default 730d, both do). The busiest-times heatmap says how far back it
+  really goes (at most `retention.hour`), and links to the Explore page
+  keep within `retention.queries` instead of assuming 7 days.
+  `GET /stats/status` and `GET /stats/explore` add `retention_seconds`.

 - A reverse zone's missing PTR records count only its own view's A and

 ### Fixed
 
+- The "query log is off" error named a setting that doesn't exist,
+  `stats.query_retention`; it's `stats.retention.queries`.
+- `jarl zone show` for a reverse zone printed only "and 1 more" under
+  "Other views:" when the server was older than the CLI (0.6.1-rc.2
+  sends the count but not the addresses). It now prints just the count
+  line then.
+- `jarl changeset show` printed its Created and Applied times in UTC,
+  while `jarl history` and `jarl status` print local time. It uses local
+  time now too.

 - The statistics' "Busiest times" grid drew hours without data taller
   than the others (they picked up the page's padding for empty
   messages).
