Fix #696

If I understand correctly how `run_hpkp()` should be displaying the list of Backups, the problem shown in the photo attached to #696 occurred because the dangling SPKIs should have been printed on the next line. This PR fixes this by changing the code that prints out the "good" backups to include a newline after printing the CA's name.

Another problem this PR fixes is that `tm_italic()` is being called instead of `pr_italic()`, meaning that the italicized text is being printed to the terminal, but is not being included in the HTML output.

Finally, this PR fixes errors in the definitions of `tmln_italic()` and `prln_italic()`. `tmln_italic()` calls `outln()` and `prln_italic()` calls `tmln_out()` instead of the reverse.
