Corrected logic within Money_tracker->save_post() that identifies if this is data from an existing entry or a new. Switched from "||" to "&&".
Account_model->get_account_id_from_entry() now returns the account ID as an INT.
* Entry_model->get_select_tags() now takes in a $col value to indicate a column.
* Entry_model->save() now saving the tag IDs collected in a 1D array, instead of a 2D array.
