Subject: - reimplemented image cache (fixes segfaults and speeds up image
 loading) - fixed a recursion wenn de-initializing ImageMagick (crashes on
 exit) - reverted the changes in ImageMagick-loader that concerned palettes  
 (obviously some versions of ImageMagick are BROKEN!!! I am using 5.5.7 which 
  works fine. Version 5.4.7 shows random errors) - reimplemented "Flush image
 cache" into the setup menu - included -lMagick into Makefile as a workaround
 for Debian (and others   possibly) - fixed display of scrollbar
