[KimDaBa] A couple more patches

[Robert L Krawitz]

1) This is the correct fix to handle .thm files (next to .crw files).
   I didn't realize that QString::baseName() strips off the leading
   directory.  I guess when I tested it I ran kimdaba out of the
   directory where the files actually lived.

2) The first block in this change flushes the thumbnail cache when the
   thumbnail size changes.  This solved a number of redisplay problems
   I was having -- not all of them, but it certainly solved a problem
   I had when I changed the thumbnail size.

   (BTW, why is the cache size of 4K hard coded?)

   The second block (that's currently #ifdef'ed out) may or may not be
   important.  It seems very strange to me to return an empty pixmap
   when it isn't found in cache, but there may be a reason why.
