* Use ecore_plugin instead of dlfcn

* the modules names are now "xine" and "gstreamer" (it's useless to add
   the extension, as ecore_plugin do not need it). I'll fix eclair,
   etk_extra and ewl.
 * look for the modules in path that is pointed by the env variable
    EMOTION_MODULES_DIR first.
 * fix a leak in the gstreamer module
 * remove some trailing spaces
