*Finally* fix 8333: "setting the home page is unintuitive".
It was both about the home button (which is fixed now) and about the startup page of konqueror (which I thought was fixed, so I closed 8333, but I then discovered that it was in fact not fixed yet, the only way to change the start page was still the unintuitive "save view profile webbrowsing").

Fixed now, the way all other browsers do it:
added a combobox in the configuration page, which says "When Konqueror starts: Show the introduction page / Show my home page / Show a blank page"

New strings approved by kde-i18n-doc.
