[PATCH] added missing methods in PerlArray, batteries^Wtests included

[St�phane Payrard]

The get_*_keyed methods were missing from PerlArray. Inheriting from Array did not
cut it when accessing elements beyond the array end.

The patch adds the missing methods.  They really are a cut and paste
from the Array methods. They access the corresponding get_*_keyed_int() methods,
or the get_pmc_keyed() methods for the next part of a composite key.
