Move HTTP response body errors into http.go

Take the errors in `main()` that check the response body contents for
known error strings and put them in their respective functions in
"timetask/http.go".

Didn't really make sense to me that these functions were returning HTTP
responses that we weren't really using in a meaningful way. Instead they
should just do their thing and let us know if there was a problem.

That includes checking to see if there were any non-standard errors,
like the ones we had custom-built. Now all that handling and
error-making is self-contained, which feels much nicer.
