HsBridge.pm for yet_another_regex_engine

[audreyt]

putter++'s YARE can be hooked into Pugs by modifying source:perl5/Pugs-Compiler-Rule/lib/Pugs/Runtime/Match/HsBridge.pm to call into source:misc/pX/Common/yet_another_regex_engine/Regexp_ModuleA.pm and use its API instead. Only the RUN function needs to be implemented -- CMD is only used when perl5 is not embedded, which is currently only during "make ghci" and can safely be deferred until later.
