<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Also the Hidden= key no longer makes sense when the metaData is inside the file, just don't install it if you don't want it there.</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
