#   loadconfig -- load configuration file
#   SYNOPSYS
#     	loadconfig($opts, $filename, \%data)
#
#   DESCRIPTION
#   	load and parse a configuration file into the data
#   	hash.  If the filename does not contain / it will be
#   	looked for in the vault if defined.  If the filename
#   	does not exist but filename.conf does that will
#   	be read.
#
#   OPTIONS
#	Options are case sensitive, upper case has the
#	opposite effect of lower case.  If conflicting
#	options are given only the last will have effect.
#
#   	f	Ignore fields in config file that are
#   		capitalized.
#   
#   	o	Config file is optional, return undef if missing.
#   
#   	R	Do not allow recoursion.
#
#   	g	Only load from global directory.
#
#	
#   
#   LIMITATIONS
#   	Only way to tell whether an option should be a list
#   	or scalar is by the formatting in the config file.
#   
#   	Options reqiring special handling have to have that
#   	hardcoded in the function.
