Bug 10490: Overdue fines cap can't store decimal values

Browse source 
When overduefinescap was added to the issuingrules the datatype
given was decimal. This translates in MySQL to decimal(10,0).
This doesn't allow you to store decimal values and therefore
values like 4.5 are saved as 5 in the database.

To test:

On a current installation:
1) Try to enter 4.5 as Overdue fines cap. Verify that the value
   is not correctly saved.
2) Apply patch and run database update.
3) Try adding/changing an issuing rule setting Overdue fines cap
   to 4.5 again.
4) Verify the value is saved correctly.

Create a new Koha installation from scratch:
1) Verify that the issuingrules table has been created correctly
   and that you can add/mofidy issuingrules correctly.

Because this bug can create data loss, the old database update
has also been changed to avoid this problem for people updating
at a later point in time. Checkout an older version of Koha
pre 3.09.00.027.

1) Run the database updates.
2) Verify again, that adding/modifying issuingrules works correctly.
