Adds the following procedures, which just call through to the `printf` versions, with `newline = true`; a new parameter
also added in this commit.
In all cases, `wprintf` is the one that ultimately writes the newline, if requested.
- printfln
- fprintfln
- eprintfln
- aprintfln
- tprintfln
- bprintfln
- caprintfln
- ctprintfln
- sbprintfln
- wprintfln
