Put relationship ahead of account name in assigned financial accounts page (CRM-12474)

Michael McAndrew pointed out that the table of a financial type's assigned financial accounts was in the wrong order, leading to "Yoda-like" displays like "Campaign contribution income type is".

This branch puts the relationship column first--both to straighten out the locution as well as to clarify what's going on: you are looking at what financial account falls in each relationship slot rather than the other way around.
