Notify KDE about changed icons using dbus

When implemented in libappimage, this should not be done using Qt, though. Unless we switch libappimage to Qt.

Reference:
TheAssassin/AppImageLauncher#165

Already investigated this and found that there are no dbus services listening to that signal. Please check the details here AppImageCommunity/appimaged#88 (comment)

Right now we don't call any desktop update from libappimage, first we need to check if we want to do it. Second we should move all the known hacks (not only kde) to libappimage

[probonopd]

Yes. @TheAssassin wdyt?

[azubieta]

Already investigated this issue and the dbus call has no effect so far.
This also seems to be a duplicated of #29
Will close the issue and the discussions about moving desktop update hacks could continue on #129
Please feel free to reopen it if required.

@TheAssassin why are you using it in AppImageLauncher?

I was told this might help in some chat, IIRC. It certainly can't hurt, I'm using Qt anyway, so DBus is easy to use.
