<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The method that returns a QList<QObject *> could/should actually go into Qt at some point. The rest is tied to our specific metadata keys, so it can't.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I am a bit concerned by KPluginMetaData vs KPluginInfo, but I lack full overview on that, maybe Sebas can comment on that part?</p></pre>

type safe accessor functions for the standard plugininfo keys that are
also used by the .desktop file based KPluginInfo
KPluginMetaData: Read the translated value for name and description
The "Name" and "Comment" fields of the metadata should be translated
since they will be shown to the user (e.g. in the plugin selection
dialog)
Add a unit test for KPluginMetaData
Add KPluginMetaData::findPlugins()
Add a unit test for KPluginMetaData::findPlugins()
Introduce KPluginLoader::instantiatePlugins() and add a unit test
This method allows easily instantiating all plugins in a given directory
KPluginMetaData::pluginName() was changed to return the base name of the
plugin file if no plugin name was set in the JSON metadata</pre>
