Changes to support the 'modules' build of the bes.

Added bes.conf.modules.in and changed both the configure.ac and
the Makefile.am files.
Fixed Makefile.am nc-conf target
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.
Merge remote-tracking branch 'origin/modules'
Fixed configure.ac after merging with the modules branch
