Changes for the 'modules' build.
Added tmp using the .gitignore trick to add empty dirs
Added bes.conf.modules.in

Needed for the modules build.
Build changes.

Tweaked	the config.status dep so that it includes $(top_srcdir).
Added the new bes.conf.modules.in to EXTRA_DIST	  in Makefile.am.
Added module name and version info to Makefile.am

This change was made to support the modules build where the autoconf
symbols PACKAGE_NAME and _MODULE are defined by the bes configure
script. This meant that the version response from the bes was useless
since it listed every module as 'bes' and gave the bes' version
number.
Fixed configure.ac after the merge with the modules branch.
