Many updates/fixes to 2018/burton2

This is a big commit but it should complete this entry and 2018 unless I
have missed something.

The make test rule was fixed. A script was not +x.

Renamed freqcount -> freqcount.sh (for browser/display).

Renamed mkkeywords -> mkkeywords.sh (for browser/display).

Renamed runtest -> runtest.sh (for browser/display).

Renamed spotcheck -> spotcheck.sh (for browser/display).

Renamed spotdiff -> spotdiff.sh (for browser/display).

Made tac.man proper man format and renamed tac.1.

Added tokcount.sh - a script that the author included in the remarks but
not in a script.

The renaming of files should be okay including the manifest (it is
believed this is true anyway).

Add try.sh script.

The READ_ME.txt was deleted as it had been renamed to author-README.txt
but the former was never deleted. This file was typo/format checked.

Format/typo check README.md file.

+[Cody](#cody) fixed the `scripthd` script (referred to `prog` not `./prog`) and
+renamed it to [scripthd.sh](/2018/burton1/scripthd.sh) to help browsers and
+GitHub as far as downloading/displaying goes.

+Cody also added the [try.sh](/2018/burton1/try.sh) script which also uses
+`scripthd.sh` to show how it differs from `prog` itself.

+[Cody](#cody) fixed the `make test` rule: it tried to run `tac(1)` (in systems
+that have that command) rather than the entry itself which is called `tac` and
+the `runtest` script (which he renamed to `runtest.sh` for download/browser
+display purposes) was not executable.
+
+Cody also renamed `manpage` to `manpage.sh` for download/browser purposes and he
+did the same with `tokenfix` to `tokenfix.sh` as well as `spotcheck` to
+`spotcheck.sh`, `spotdiff` to `spotdiff.sh`, `freqcount` to `freqcount.sh` and
+`mkkeywords` to `mkkeywords.sh`.
+
+Cody also made the man page properly formatted for `man(1)` and renamed it the
+file `tac.1`.
+
+Cody also renamed `discrepancies` to `discrepancies.md` and made it markdown
+format.
+
+Cody added the [tokcount.sh](/2018/burton2/tokcount.sh) script which was
+included in the remarks of the author but not an included file.

+Finally Cody added the [try.sh](/2018/burton2/try.sh) script.
