v0.12.110: @newsroom.ux: a setting, a live line, reading by pace, and no jump

After a day of use, Dinis asked for five changes to the reading views, and they are here. The view of what was read is now a setting in the chip's panel (a Settings tab: six views for every article, each with what it does, and a choice for one article), not a bar across the top. The margin line changes colour as each section is read, from the pale rule colour to the accent, with a tick when a section is read in full and on the chip when the page is. Faded fades only sections read in full. Text scrolled past no faster than 450 words a minute counts as read, either way; a faster scroll counts nothing. And the jump when scrolling back up with a fold view on is fixed: it came from sections being asked one at a time whether they were on screen while the ones above folded, and from corrections made under a scroll still in motion; a fold now waits until the page is still and the words on screen stay where they are, which a frame-by-frame test in a real browser now holds.
