Add set_balance to FinancialTransactions#new_collection (fixes #438)

Browse source 
A new checkbox will allow user to set the balance to a given ABSOLUTE value
in addition to changing it by a RELATIVE value. This can be used if the
balance is tracked outside of foodsoft and should be syncroniced or for
setting the balance to zero for multiple ordergroups.
