- more highlight on "applications that use a certain KIO", Konqueror is "just" an example of such applications;
- specify KIO in addition to Konqueror in the user agent;
- remove few possible references to KDE-as-the-destkop;
- general cleanup of various user messages (configuration modules headlines, help messages);
- fix the HTML tag inside quickHelp() messages (move <h1> outside <p>);
- remove the reference to contents which has not be available for a long time into the kcms_smb (which should probably be moved under kio-extras with kio_smb).
Some of the kio_http references can be slightly less clear than
before, but KIO for sure can be used without Konqueror, so this
is a step forward.
