End every template file with a newline

Fifteen templates ended without a final newline, so they were not text
files by the POSIX definition: tools that read whole lines, including
sed, wc -l, read and shells' command substitution, drop or mangle the
last line, and diffs of them carry a "\ No newline at end of file"
marker that hides which side changed.

Add the newline. The gemtext output may not change, so the four
templates whose last action is emitted verbatim into a capsule page
trim it away again with "-}}". The templates that end by closing a
define block need no marker, since the newline then falls outside the
block and is never executed, as section.gmi and single.gmi already
showed.

The capsule builds byte-identical gemtext and the feeds are unchanged.
Web pages gain the trailing newline their templates now have, which
ends the generated HTML with an EOL too.
