Re-apply changes reverted in r20251. The only difference between this commit and r20207 is that, contrary to the recommendation given in gnc-tree-view.h, "Use GNC_TREE_VIEW_COLUMN_DATA_NONE if you plan on using a non-model data source for this column", it cobtinues to use "GNC_TREE_MODEL_ACCOUNT_COL_TAX_INFO". Using "GNC_TREE_VIEW_COLUMN_DATA_NONE" generates problems later in the "gnc_tree_view_add_text_column" routine when it tries to set up sorting for the column ("CRIT <Gtk> gtk_tree_sortable_set_sort_func: assertion `sort_column_id >= 0' failed").
Define a new column, GNC_TREE_MODEL_ACCOUNT_COL_TAX_INFO_SUB_ACCT, in gnc-tree-model-account.c filled with gnc_ui_account_get_tax_info_sub_acct_string.
Modify gnc-tree-view-account.c to define a tax_info_data_func that displays only the the data in the GNC_TREE_MODEL_ACCOUNT_COL_TAX_INFO model column if the row is expanded; otherwise it combines it with the data in the GNC_TREE_MODEL_ACCOUNT_COL_TAX_INFO_SUB_ACCT model column. Modily the view creation function to use the new tax_info_data_func for the text after having first set it to GNC_TREE_MODEL_ACCOUNT_COL_TAX_INFO to prevent the problem mentioned above, thereby overriding it.

Revert changes made in gnc-ui-util.c in rev 20039 and instead put those changes in new function: gnc_ui_account_get_tax_info_sub_acct_string.
