KApplicationTrader API

I'd vote for lambda/function object/callable (hello std::invoke in KF6?). If a 
more terse syntax is needed, it could be later provided with an eDSL along the 
lines of:

KApplicationTrader::query(name.contains("km", Qt::CaseInsensitive));
KApplicationTrader::query(
        filter::name.endsWith("km") &&
        filter::showInKDE);


> auto offers = KApplicationTrader::query(...);

+1, no need to put everything in an object.

I'm aware I voted for the most-porting-effort solution ;)


Cheers,
