- Helios::Config:
 - added get/set/unsetParam(), which all work directly on the
   contents of HELIOS_PARAM_TB in the collective database.
 - parseConfDb(): combined the 2 separate database queries
   into 1 to reduce database calls when config is updated.
 - separated Helios config parameter documentation into
   Helios::Configuration POD.
- Added: helios_config_get.pl, helios_config_set.pl,
  helios_config_unset.pl, helios_config_import.pl to enable
  config subsystem to be easily used in shell scripts.
- Makefile.PL:  Added all *.pl commands above and
  helios_jobtype_add.pl to EXE_FILES.  Removed old LICENSE line.
Changed --help handling to use Pod::Usage

	- Helios::Config:
	  - NEW set/get/unsetParam() methods to more easily work
	    with individual config parameters in the HELIOS_PARAMS_TB
	    table.
	  - NEW helios_config_*.pl commands to make Helios config params
	    more accessible to shell scripts and other utilities.
	  - parseConfDb(): combined the 2 separate database queries
	    into 1 to reduce database calls when config is updated.
	  - separated Helios config parameter documentation into
	    Helios::Configuration POD.
 	- Helios::Service:
	  - Added JobLockInterval() functionality to control the
	    amount of time jobs are locked from a Helios API.  Previously,
	    the only way to control the amount of time jobs were locked
	    was to override TheSchwartz::Worker's grab_for() method.
	  - Changed hostname lookup handling to reduce the number of calls
	    to Sys::Hostname::hostname().
	- helios.pl:
	  - Changed cmd line option handling so --help and --version work
	    again.
	  - Added startup message to report the dsn of the collective
	    database helios.pl is connected to.
	  - Replaced most Error module-based try {} blocks with eval {}
	  - Updated POD with new cmd options and referenced
	    Helios::Configuration.
	- Helios::Job - replaced usage of Helios::TheSchwartz with the
	  new Helios::TS class.
	- Helios::JobType - added debug() accessor method.
	- Makefile.PL:  Added all helios_config_*.pl commands above and
	  helios_jobtype_add.pl to EXE_FILES.  Removed old LICENSE line.
