[KPhotoAlbum] Patch to allow setting thumbnail size

[Robert L Krawitz]

Here's a patch to enable setting the thumbnail size from the dialog.
I find this useful so that I can choose whether to see many small
thumbnails or fewer large ones.  The tooltip preview isn't really what
I want (I've never used it -- I have tooltips turned off anyway).  I
renamed "Preview image size:" to "Tooltip preview image size:" to make
it more apparent what it is.

BTW, it appears that startup has slowed down somewhat recently,
although I'm not absolutely positive of that.  It *may* have happened
after I rescanned for images and it picked up some videos I had.
