change address block 
https://github.com/maine207/aspen/issues/issues/issue/54
Added an option to include special fee types of BFW, DIS, and DNS, when
running the Outstanding Fee Statement, Student Fees and Obligations
Letter, and Student Fees and Obligations Letter [West] reports. Also,
cleaned up the code in these reports so that they are more similar to
each other. This was done for consistency.
