Wrong plugin settings filename

[crazybyte]

Hello,

Because in the plugin source code the preferences filename for getting the settings modified by the user is wrong the plugin cannot find the newly modified settings (it falls back to the default values that are included in the source code).
Due to this small bug the plugin doesn't show anything else but functions that are part of the 2 and 3 sections of the man pages.
