Subject: [cover] Make uncovered lines searchable in html output

Prior to PR#1807, uncovered lines could be found by searching for "
0.." in the HTML page generated by cover:analyse_to_file/1,2. The pull
request removed the two dots after the number of hits, which makes it
much harder to find the uncovered lines.

This commit introduces a sad face, :-( , instead of the single 0
character, which should make the search easier.
