qt: Add separate logging category for result of config loading
* lang/qt/src/qgpgme_debug.h: Make include guard match file name. * lang/qt/src/qgpgme_debug.h, lang/qt/src/qgpgme_debug.cpp (QGPGME_CONFIG_LOADING_LOG): New. * lang/qt/src/qgpgmenewcryptoconfig.cpp (QGpgMENewCryptoConfig::reloadConfiguration): Use new logging category.
Use a separate logging category for the extremely noisy logging of
the result of config loading to make debug logging more useful.
