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

[Shawn Willden]

Bug 136955 has a patch attached that seems like a good idea to me.  Can anyone 
think why it wouldn't?  Personally, I think it's a bad idea to have misnamed 
files, but if it's possible to handle it gracefully, why not do it?

Here's the text of the bug report:

files named pict000.jpg or Akademy2005.png etc. are imported correctly, even 
if they are wrongly named and in reality both image/tiff, but Sol-2002.01.04 
or Judy.image are not (both image/png).

And the patch is at:
