Review request for KDE Frameworks and Martin Gräßlin.


Changes
-------

Fix all the issues


Repository: knotifications


Description
-------

This patch reduces the dependencies of KNotifications framework and effectively makes it a tier 2 framework.

KService is used only for locating additional notification plugins and to my knowledge,
there are none such plugins currently existing, at least not in all around KDE plus
the class for the plugins wasn't exported until about two months ago, so this should
be safe without a legacy support.

KIconThemes is used only to get "KIconLoader::Small" icon pixmap for notifications
using KPassivePopup. After some playing around it turns out that it puts the icon into
the KPassivePopup title and makes it as big as the text. So I've made the icon size to
be the same as the text height. So this keeps things visually the same + still DPI aware,
though I believe the KPassivePopup should receive a complete visual overhaul anyway.

Additionally, KCodecs dependency has again one single usage for decoding html entities
to QChars within QXmlStreamReader parser, so eventually could also be removed/replaced
with QTextDocument::toPlainText() which seems to do the same job as QXmlStreamReader+KCodecs.

Everything still compiles + I added a test for KPassivePopup with an icon.
