Fixes to thanks for fixes file
At least one entry was missing (1984/anonymous). Some entries were removed. One such entry was not ever broken but instead when I had renamed a file (to markdown) I forgot to update the DATA variable in the Makefile which then broke compilation. This was seen in the log and mistakenly believed that there was something wrong with the entry when there wasn't. Other entries removed were not fixes but notes. Various README.md files have been updated for this sometimes just formatting merely because I opened the file because for instance there is an alternate version (many by me) that is referred to. I'd not be surprised if more README.md files have to be updated for this much better system but these will be found in time when I do another pass (and some years I have not checked at all yet).
