Bug 11633 Return Correct status if patron blocked by fines

If the patron has amassed charges that block borrowing, but we
allow staff override the information that the patron cannot
issue should be included the patron information response

This patch sets the appropriate status fields in the patron object

It restores the fee_limit member to the patron object
and calls a local subroutine to set it.

This could be done more elegantly but that would require more
major refactoring of the rather messy initializer code
in ILS::Patron
