New driver for Vlsys mplay (the one in Zalman Hd135 case)

Hi,
 
 In case anyone is interested, I've written a lirc driver for the receiver
that
 come with the Zalman Hd135 which appears to be a Vlsys Mplay Blast.
 I join the driver and a patch for lirc-0.8.2 (configure.in,
daemons/Makefile.am
 and daemons/hw-types.c) and my lircd.conf for this remote.
 I don't know how to add my driver to the lirc configuration interface. If any
 body can explain it to me, I will do it with pleasure.
 
 I hope this helps someone out,
 Benoit
