+Subject: [PATCH] [PATCH]: Change path variable for loading plugins.
+
+Remmina is coded to load plugins from path (REMMINA_RUNTIME_PLUGINDIR)
+provided during compile-time. This causes cycle between outputs 'out'
+and 'plugins'. Therefore, code it to load plugins from path
+(REMMINA_PLUGIN_PATH) provided during run-time.
