• One entity on several tiles (GitHub #83). A light can now be a small tile on page 1 and a tile with its slider on
  page 3, a camera can be on two pages, and a whole page can be copied with its tiles. Every copy has its own name,
  icon, colour, size and tap. The library keeps offering an entity that is already on the screen and marks it with a
  check, or with how often it is there. Only the bedside clock is on a screen once. It needs firmware 0.16.0; an older
  screen asks for its update first.
• On firmware 0.16.0 a lock's "tap again to unlock" counts only on the tile you tapped, an alarm going off opens its
  card once, and each copy of a camera on a page gets its own picture and its own fit.
• A lock or alarm panel no longer keeps a pulsing ring after it settled while its page was out of view. The ring stayed
  with the place on the screen instead of the tile, so a page that came back could show the old animation.
• esp_screens_add_tile now always puts a new tile on the screen, also when the entity is there already. To change a
  tile through an event, remove it and add it again. On firmware older than 0.16.0 it works as before.
• Tested: tools/check.sh with new tests for copies (validation, tile events, delivery to old and new firmware, live
  pictures by tile, page copies, the editor's library and page menu). On a Guition 4848S040 with firmware 0.16.0 and a
  Home Assistant OS bench: a lamp, a lock, an alarm panel and a camera on several pages, a whole page copied in the
  editor, and a page with the same camera twice. A lamp switched in Home Assistant changed on every copy, also on a page
  that was not on screen; tapping one lock copy and then another did not unlock, and each copy kept its own "unlock
  never" setting; the alarm going off opened its card once; each camera copy and each album cover copy showed its own
  fit, name and tile colour. A screen put back on firmware 0.13.0 was asked to update first and got nothing, then took
  the layout with copies once it ran 0.16.0 again. Checked by hand on the Guition and on a CYD ESP32-2432S028R: lamp
  copies switch together, a lock opens only on two taps on the same copy, the card and the effects page of a copy carry
  its name, and an alarm going off opens its card once on each screen. Every board builds; the CYD firmware is 16 bytes smaller
  than 0.4.25's (91.2 % of its slot).
