Game of Life page element and built-in page

A new page element runs Conway's Game of Life in an area (the whole display
by default), one per page. Start: random dots, one pattern, or the icons
whose names start with a text in turn or in random order. Edges: wrap
around, dead, or a hidden margin where gliders fly out of view (leftovers
that stay put in the margin are cleared, so a glider gun runs cleanly).
It restarts when the board is still or repeats within 16 generations
and/or after a number of generations, after a hold time (an empty board
at once).

logic/life holds the board and timing (tested), display/life_player runs
the board of the shown page, ticked before each frame; frames are paced
like scrolling text. The element reuses existing fields, so the page
format stays the same. The Icons tab has a library of 17 LifeWiki
patterns (checked with a simulation), and the built-in page "Game of
Life" shuffles through the life_ icons. About 12 KB flash, 8 KB RAM.

Version 2.17.0, tested on the display over OTA.

 - Pages hold 16 elements (format 7). A `DynamicPage` is about 4 KB: allocate it with `new`, and reset
   it with `clearPage()`, not `page = DynamicPage()` (a temporary on the 8 KB loop stack).
+- Game of Life (`logic/life`, `display/life_player`): a page element without fields of its
+  own: it reuses `bar_width/bar_height` (area), `format` (edges), `input_unit` (start),
+  `text` (pattern / name start), `factor` (density), `scroll_speed`, `auto_unit`, `target`
+  (max generations), `bar_max` (hold s); the list is in `logic/page.h`. JSON adds `start`
+  and `generations`. One per page: `LifePlayer` keeps one board (about 7.5 KB) and ticks it
+  in `FlipdotFrames::dynamicPage()`; reloading a page with the same start
+  (`sameLifeStart()`) keeps it running. Rotating lists the icons only when
+  `iconListRevision()` changes. The pattern library (RLE) is in the web page; check new
+  patterns with a simulation before adding them.
 - HA attributes may be paths into lists (`forecast.1.condition`, `net/ha_api`). The
