Add a new color format seen on my Galaxy S3
(OMX_SEC_COLOR_FormatNV12Tiled = 0x7fc00002) to the table,
but don't actually implement it - the decoder doesn't choose it.
Remove an assert that makes the plugin fail noisily and take the app down
if it sees a color format it doesn't recognise (just skip the codec instead)
Modify the debug output when plugin scanning to print color format info to
make this sort of thing easier in the future.
