Make award titles more consistent

A lot of the award titles that had more than one word capitalised were
changed to just one word capitalised, the first. Some were changed to
have multiple words capitalised. This happened when it was something
like '... prize' or '... award'. An exception to this is 2020/ferguson1:
'Don't tread on me award'. This is because I am not quite sure if I like
'Don't Tread On Me Award' or if it should be 'Don't Tread on Me Award'
(probably not that). For some like 'Grand Prize' or 'Bill Gates Award'
it's simple but I'm not so sure for my Snake entry of 2020. I will try
changing it and comparing it side-by-side to see which looks nicest.

This commit should make it easier to update the form of the award titles
in that they should all be consistent (or more consistent if not
completely) though it should be noted that the macOS Numbers application
(spreadsheet) is case-insensitive. A reason I did not change 'Don't
tread on me award' to 'Don't Tread On Me Award', yet, besides the above
reasons, is that it's a longer title and I am not sure how I like that
many words capitalised. Still it's a title of a slogan/whatever so it
might be better that way. This will be determined in the near future.

The tmp/year_prize.numbers had the text size increased a fair bit as
the default is too small for my pitiful vision (I changed it within
reason as it can become harder in another way if it's too big - 16"
MacBook Pro screen). One of the columns was also widened as it was too
short even for the smaller size.
