* Remove all but two of the subdirs in krita/core in preparation for more
  file shuffling -- I will take Jesper Pedersen's lessons to heart and
  separate interface and implementation for core and plugins
* Remove all necessity for plugins to include headers from the tiles 
  directory (tested for performance consequences, the current scheme
  is even slightly faster)
* clean up convolution by removing the old matrix class
* clean up Makefile.am's by only linking with the necessary libs, not
  always with kofficecore and kopainter.
