haserl: uptate to 0.9.32, add optional lua support

This patch updates haserl to version 0.9.32 and introduces optional lua support
See http://haserl.sourceforge.net/manpage.html#lbAM

Note: to implement lua support I had to change build process slightly to
get rid of host precompilation of lua script. I decided to patch existing
Makefile.in instead of patching Makefile.am and regenerating everything
from scratch.  If this approach is wrong and it's better to patch Makefile.am,
please let me know.
