Version 0.9.2

Added: New troubleshooting options have been added to the Configurator that can be tried in case of problems.
Improved: E-APO is now normally always installed as LFX/GFX, also in Windows 8.1 and later, to avoid problems with some applications bypassing SFX/MFX APOs (e.g. Skype).
Fixed: If the input channel count was higher than the output channel count and there was no child APO, Equalizer APO could crash during initialization.
Fixed: If a file in the config path was only renamed (not modified), the configuration was not reloaded.
