Bug 13590: Add ability to charge fines at start of charge period

Right now, Koha only charges fines at the end of a given charge period.
For example, let us assume a circulation rule has a charge period of one
week ( 7 days ) and a fine of $5. This means that an item can be overdue
for 6 days without accruing a fine. Koha should allow circulation rules
to be configured to place the charge at the start of the end of the
charge period so the library can decide when the fine should accrue.

Test Plan:
1) Apply this patch
2) Run updatedatabase.pl
3) prove t/db_dependent/Circulation_Issuingrule.t
4) prove t/db_dependent/Circulation.t
5) prove t/db_dependent/Fines.t
6) Ensure you can still create/edit circulation rules

Edit: I removed the DBIx changes after a couple minutes fighting with them.
Will regenerate as usual in a RM followup / Tomas
