Changelogs for appfinder, exo, utils, mcs-plugins, mcs-manager,

xfce4-session, xfce4-mixer, thunar, libgui, xfwm4, the panel, 
orage, trigger-launcher and terminal updated.
Also couldn't resist to fix a small error in the xfce4-mixer
Changelog.
Didn't updated the changelog of xfprint, because I discovered
that that translation wasn't updated, it had just slipped through
the commit by mistake.
