Changes for the modules build.

Modified the Makefile.am files, configure.ac and tweaked the
bes tests so that they use a bes.conf file built using either the
local configure (standard build) or the bes configure (modules
build).
Removed hdf4 and hdf5 from the bes.conf build with from the bes
modules branch build until those are working. Added the handler's
conf file to gitignore.
Fixed the modules branch bes.conf file.

The bes.conf file used with the bes modules branch now uses
the hdf 4 and 5 handlers, so all of the tests work.
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, Makefile.am and bes.conf.in after merging with 'modules'
