Fixed (I think) a double free or corruption bug in acpustatus.cc
Reverted old flashblock fix because it stops Qt5 apps from creating
windows, because Qt5 embeds every window.
Give nice names to the .desktop files, because display managers that
use the name property show both icewm-session and icewm as just
"icewm."

Now they should show up as "IceWM Session" and "IceWM", respectively.
Merge branch 'icewm-1-3-BRANCH' of https://github.com/mrbrainsample/icewm into icewm-1-3-BRANCH
