Change 'Best of show' to 'Best of Show'

This fixes an inconsistency in case. The spreadsheet in tmp,
year_prize.numbers and the year_prize.csv files were updated also (with
the ./fix_csv.sh run under tmp/).

There was no need to manually update the index.html, any other html
files or .entry.json files as I used sgit(1) to change the case.

tmp/year_prize.csv
