Changes to a number of kanji.

I went to the whole collection and looked at all kanji in a [colorized](https://github.com/cayennes/kanji-colorize) version, and noted all those where the numbers and the colors did not match. This should fix most of those problems, and also a few others.

* A lot of fixes of the internal stroke order (used by colorizers, animatiors).
* Fix the printed numbers for some.
* Moved a few numbers a bit.
* Added a few numbers that were missing.
* Straighten some central vertical stroke of 鬼 elements.
* Changed some kanji to the long horizontal stroke variant of 巨
* Cleaned up a 舛 radical where the version to use was clear.
* Renamed a kanji. middle first is standard, left first is a possible variant.

Most changes are to non-jōyō-kanji, and often only to variants.
