*fixed crashes on category add/delete/rename *changed icon of category rename and mapped triggers +/-/1 to the buttons *fixed green bar flash on game start *fixed freeze in STATE_DISABLED when leaving->entering->saving game settings *separated a few settings from the GUI setting and created a "Feature" settings menu *Updated language files *Added Wiinnertag support. NOTE: When you enable the Wiinnertag in the settings a prompt will come up if the Wiinnertag.xml does not exists in the setup path for it. This prompt will ask you if you want an example file created by the loader which you can adjust to your account (I suggest you create one on first use). Multiple/Other tag sites can be setup in the xml file and loader will execute them all one after another. Also Wiinnertag requires a network connection established to be working. When you enable this feature and auto network init is disabled you will be prompted to enable it.
