Originally Cat's smilies for Fcitx IMF, add some other smilies collected from Google+.
put QuickPhrase.mb to $HOME/.config/fcitx/data, if you already have your own QuickPhrase.mb, just add these lines to your QuickPhrase.mb. You may need to install Dejavu fonts to support some utf-8 glyph.
Activate IME and then press quick input key to type these smilies.
Enjoy!
