Add App.save_parameters or export_parameters
Depending on the file extension in provided path, this function could save App settings to xml or json, yaml, etc using summarize().
Should not require external dependencies (xml, yml and json are builtin).
To be honest I don't think a lot devs are using XML app exports, but it could be nice to support this anyway.
And python's builtin xml parser is a nightmare
