remove new post log

return to correct number of preview posts e.g. if post has less/no preview replies

add hotThreads function from ptchina, needs some more work :)

See merge request fatchan/jschan!250

property name fixes/change, category -> type, type -> range, now they reflect more what they actually are
bantable updated, bit cleaner mixin
bantables now more compact, will overflow (with scroll) and no text wrap
close #446

The ban table now has a column or whether a ban is of an IP or Bypass ID. (Or pruned IP, if you were dumb enough to ban one of those)

Fix/improve showing new modal bans, now handled by time.js to show "relative time" or other time settings.
Uses a new 'showModal' customEvent that can probably be used for other things down the line.

ref #445

bit simpler deleting of quotes in deletepost.js, simple string repacement instead of remarking the whole post.
and refactor the deleting to return the bulkwrites
partly related to #215, moveposts/editposts it makes sense to remarkup because in those case we can even be adding quotes.

update deps and package(-lock).json

bugfix already appealed bans showing as "appealable"
minor ban form/ban mixin tweaks
no more sketchy way of "clearing" the form and resubmitting to show bans page. nice!
