Man page for bfbin2sqlite3

Wrote a man page for bfbin2sqlite3.  Additionally, normalized all man
pages to be in the category "Byfl tools" and to use the current SHA-1
value for Git HEAD (the short version) as the version string.

Renamed bfbin2text to bfbin2csv and wrote a man page
Corrected binary Basic Blocks output

The binary output of the Basic Blocks table was egregiously wrong,
with many columns out of order with respect to the column names.  This
revision straightens those out.

It also looks like I forgot to include bfbin2csv.pod in the previous
commit.  It's included here.
