Bugzilla Bug 174248

Not having useflag kde when installing app-cdr/k3b has the unexpected effect of
not installing k3bSetup. This is quite confusing for an end user, especially
since the k3bSetp tool is heavily advertised in k3b and it is nowhere to be
found for no apparent reason.

Suggests adding/changing the useflag to k3bsetup to give users a clue about
what the effect really is.

If the above is not considered reasonable, at least an elog message should be
added that explains the situation.

Reproducible: Always

Actual Results:  
Confused users because of an inappropriately named useflag/useflag-function

Expected Results:  
A clear & understandable k3bsetup useflag

I've added an elog message. It's pointless to add yet another use flag for
every minor crap. Add yourself to the cdrom group and you're done. No need for
k3bsetup.

OK, sounds like a reasonable solution that solves the main problem of the user
not knowing what is going on. Thanks :)
