FIX GS MediaPortal with some (most) skins
MediaPortal uses since past versions its own VirtualKeyBoardExt .
Unfortunatly VirtualKeyBoardExt does not expect the images in same location as regular VirtualKeyBoard.
VirtualKeyBoardExt:
key_bg = LoadPixmap(cached=True, path=resolveFilename(SCOPE_CURRENT_SKIN, 'skin_default/vkey_bg.png'))
