* treestore.c (tree_store_save_to): Moved the functionality from tree_store_save() to here. (tree_store_save): Save the tree in the default location in an atomic fashion. (tree_store_load_from): Moved the functionality from tree_store_load() to here. (tree_store_load): Load the tree from the default location. * treestore.h (MC_TREE_TMP): Added a #define for the temporary name we'll use when saving the tree. Moved the #defines from tree.h over to here. * main.c (main): Use tree_store_load() and tree_store_save(). Removed the mc_tree_store_load/save() versions. * tree.c (load_tree): Use tree_store_load(). (save_tree): Use tree_store_save().
