Bug 10664: fix error in overdue_notices.pl if there is no active currency

If there is no active currency, when running overdue_notices.pl
you get a sofware error "Can't use an undefined value as a HASH
reference" on GetCurrency() function call.

With this patch, if there is no active currency, fines are formated
by default 0.00 and notices are correctly generated.

Test plan :
- have at least one borrower with overdue that should trigger a notice
- verify that there is no active currency (Adminitration > Currency &
  Exchange rates)
- run misc/cronjobs/overdue_notices.pl -v -n (to get the notice directly
  on output)

=> without the patch you get the software error
=> with the patch, notices are correctly generated

If an active currency is defined, the script overdue_notices.pl runs
the same with or without patch

Bug 10745: remove more ambiguity for translators for XSLT subfieldSelect parameters

As in Bug 6278, this patch replace ">at<" with ">a_t<"
so not to mislead translators. Found more cases that
initial description.

To test:

1) Check that problem exists and only on xslt files,
using your preferred language

egrep -B10 "^msgid \"at\"" misc/translator/po/xx-YY-i-staff-t*

2) Apply the patch

3) Update translation file
(cd misc/translator; perl translate update xx-YY)

4) Verify the problem is gone, repeat 1

5) If you like verify new entries in PO file

egrep -B15 "^msgid \"a_t\"" misc/translator/po/xx-YY-i-staff-t*
