feat! docgen always outputs a document

We have long had a feature for docgen that checks the time stamps of
all input files and the output file and avoids running Pandoc to
produce the output file, if the output file won't change. This has
always been a little imperfect: sometimes the output file would change
due to other changes than what's in the input files. For example, when
Pandoc changes, or when Subplot code changes. This has led to
surprised users. We no longer user Pandoc at all. Drop the time stamp
checking functionality and have docgen always write the output file.

-## Avoid changing typesetting output file needlessly

-This scenario make sure that if docgen generates the bitwise identical
-output to the existing output file, it doesn't actually write it to
-the output file, including its timestamp. This avoids triggering
-programs that monitor the output file for changes.
