Fix for freeing node trees that are part of other data blocks (material, world, lamp, texture, scene). These node trees were not properly freeing the IDProperty data, due to not being called from BKE_libblock_free.

Now there is an extra function BKE_libblock_free_data, which is called explicitly in ntreeFreeTree if the tree is not part of the library data (ntreeCopyTree does a similar thing using BKE_libblock_copy_data).
