SUMMARY All the apps should provide the AppStream Metadata file (appdata.xml) file with a description, that contains the about information too. But when we're creating the about dialog, in most cases we have to put the same information there, but in code. And it's pretty problematic to update the information and keep in sync in both places. So, the idea is to create a function like `KAboutData::setDataFromFile(string filePath)` that will read the XML file and fill the all values from there.
