Convert abc to nqp-rx

[fperrad]

The language abc (in examples/languages/abc) must be converted with nqp-rx.

• step1 : actions.pm which currently uses nqp
• step2 : grammar.pg & grammar-oper.pg which currently use PGE

[fperrad]

Currently, nqp-rx fails to compile actions.pm

C:\fperrad\Parrot\trunk\parrot-nqp.exe --output=src\gen_actions.pir \
            --target=pir src\parser\actions.pm
Obsolete pod format, please use =begin/=end instead at line 4, near "head1 NAME"
