[KPhotoAlbum] Checking image file readability by MIME type, rather than file name

[Jesper K. Pedersen]

I wonder if KImageIO::typeForMime is expensive - afterall it needs to read 
some of the file.

A solution might be to do something like:
return KImageIO::canRead(KImageIO::type(fileName)) || 
KImageIO::canRead(KImageIO::typeForMime(KImageIO::mimeType( fileName )))  ||  
ImageManager::ImageDecoder::mightDecode( fileName );

Thus first checking using the file name, and if that fails trying using the 
(presumeably) more expensive one.

Cheers
Jesper.
