Fixes for BUNDLE_SRC builds.

FreeImagePlus didn't have its library paths being set properly and
the _TESTING targets were failing because they assume USE_BUNDLE_SRC isn't
being used.
Made SET_TARGET_OUTPUT_DIRECTORIES exclude the runtime directory.

The runtime directory should remain the same as that of oce so that dll's
are put in a location were they can be used.
Fixed cmake issue where the .dll copying for testing wasn't occuring at all for USE_BUNDLE_SOURCE
Removed SET_TARGET_OUTPUT_DIRECTORIES.

This MACRO isn't needed since none of the oce-win-bundle packages override these
settings. The default values will simply be inherited.
Modified the .lib definitions to discover the library using ARCHIVE_OUTPUT_DIRECTORY.

Also removed BUNDLE_LIBRARY_RESULT_DIRECTORY which is no longer used.
