Installing header files to ${INCLUDE_INSTALL_DIR}/tde
added another subdirectory layer that caused build failures
in certain apps such as kipi-plugins.
This partially resolves bug report 600.
This will probably require some tweaking before it will build under Qt4,
however Qt3 builds are OK. Any alterations this commit makes to kdepim
behaviour under Qt3 are unintentional and should be fixed.
