Changes from 1.0

Fixed bug that caused problems with palette.  Thanks to Philippe
Thomas for the bug report.  
Fixed really stupid bug that caused images with a depth lower than
4 bits per component to crash - thanks again to Philippe Thomas for 
the bug report.  
Added progressive and PNG`s own Adam7 interlace format support
through the MEDIAStream format.  If you want your application to 
support this, please request the image as a DATA_MEDIA, be 
prepared for this to fail and to re-request as a DATA_BITMAP.
Added interlace and more depth options to preference view.
Fixed grayscale images, they are now returned as a B_RGB_32_BIT 
bitmap.
Linked against latest libpng 0.96 and zlib 1.0.4.
DR9 version.  Better error handling.  Additional type checking in
Identify() function.  Fixed 8 bit input data for save routine.
Added some text comments to images.
