Subject: smiley: warn instead of error for missing smileys
X-Git-Url: https://sipb.mit.edu/gitweb.cgi/ikiwiki.git/commitdiff_plain/df5de5b967a1e6e14161fd1269efe5b17d33eec1

smiley: warn instead of error for missing smileys

A missing smileys.mdwn caused the plugin to error out interrupting the
building process. Instead, we check for the file presence and warn without
erroring out in case it's missing, in a similar fashion as it's
currently done for the shortcut plugin.
