Moving some code from tree to model where it belongs. Fixes some CPU usage

2007-12-14  Sankar P  <psankar@novell.com>

	* em-folder-tree-model.c: (emft_model_unread_count_changed),
	(em_folder_tree_model_init),
	(em_folder_tree_model_set_unread_count):
	* em-folder-tree.c: (em_folder_tree_construct):
	Moving some code from tree to model where it belongs.
	Fixes some CPU usage issue whenever (un)read count is updated.
	Hopefully no regresssions.
