Subject: [PATCH] Don't use KIO copy and QTemporaryFile to load xml definition
 files.

Since files are usually (maybe always?) local anyway, there's not
much reason to copy the file to a temporary file.
This also fixes QDomDocument::setContent failing on an empty file
when the QTemporaryFile is somehow empty after the copy has finished.
