Added missing post-compile move.
Changed to copy, just in case something uses it.
Added a conversion of the Erlang .hrl file.

The LFE file works around an issue in LFE where records with no fields cannot
(yet) be defined. The rabbit_framing.hrl file defines several records with this
characteristic.
Added a conversion of the amqp_client.hrl file.

This one does not include the problematic rabbit_framing.hrl file, but rather
the LFE rewrite rabbit-framing.lfe. I need to open a ticket in the LFE project
to ask this issue to be addressed.
Updated to include non-problematic include file.
