Comment(by hobarrera):

 As a note for whoever implements this, this requires moving:

 certificates/  ->  $XDG_CACHE_HOME/purple/certificates/
 icons/  ->  $XDG_CACHE_HOME/purple/icons/

 logs/  ->  $XDG_DATA_HOME/purple/logs
 smileys/  ->  $XDG_DATA_HOME/purple/smileys
 blist.xml  ->  $XDG_DATA_HOME/purple/blist.xml
 xmpp-caps.xml  ->  $XDG_DATA_HOME/purple/xmpp-caps.xml

 Everything else already in .purple should move into
 $XDG_CONFIG_HOME/purple

 The default fallbacks (in no enviroment variable are set) are:
 $XDG_CACHE_HOME -> $HOME/.cache
 $XDG_CONFIG_HOME -> $HOME/.config
 $XDG_DATA_HOME -> $HOME/.local/share

 I hope this helps, here's the spec in case you prefer to read it:
 http://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html
 Cheers!
