-updating to ppc r32 and libogc 1.8.20 changed the reset button callback which caused wiiflow lite to freeze in wiivc mode. fixed it by skipping it when in wiivc mode. no problem since the wiiu doesn't have a reset button.

-fixed to compile with ppc r32 and libogc 1.8.20

-fixed exiting wiiflow lite in wiivc mode so it doesn't black screen the wii u and require it to be unplugged.

-added libwiidrc so now wiiflow lite can be injected in a wii u wiivc game and will run with the gamepad.

-reverted changes of r1156. readded libwupc.

-Removed LibWUPC now that Libogc supports WiiU Pro controller.

-now cache covers also cache's banners for wii and channel games.

-fixed downloading custom banners. thanks Larsenv for the new banner repository and the link! i didn't notice it was banners before and now its banner.
