First stab at implementing array() function and '=>' within pipp.

Changes made:

* src/pct/actions.pm: added following methods: instantiate_array(),
array_arguments(), key_value_pair()

* src/pct/grammer.pg: added following rules: instantiate_array,
array_arguments, key_value_pair.  Amend term rule by adding
instantiate_array rule.

* src/common/builtins:  added sub 'infix:=>'

* src/common/php_array.pir: added sub 'array'

* t/in_php/array.t: added 3 tests for array()

TODO:  Add type checking of key values

Thanks
