Update GajimCommunityArt to new emoticons.py format
Format for emoticons has changed in #3696 (closed). We have some iconsets in http://trac.gajim.org/wiki/GajimCommunityArt . They are in older format. As we have an auto conversion code in [9474]; we should keep old version in the wiki page until 0.12 is included in most distributions. Then, change their format.
