Configuration: simplified commented namelist settings at the end of a group by adding a special variable '.end'

Namelist groups may be disabled by setting the special variable '.hide' to 'true'. This allows to selectively re-enable groups in higher order config files by setting '.hide' to 'false'

Configuration: changed handling of remove lists to not remove the .remove entries from config; used to break handling of remove lists in standalone calls to format_namelist

mkexp: changed 'get_file' function to return unknown variable references unchanged, added 'get_dir' function, returning the path for a given 'files' section

mkexp: changed 'list' filter replacement to map the empty string to an empty list. Added option to keep empty string as singleton list if needed

mkexp: reading of EXP_DESCRIPTION from initial comment now also discards leading and trailing lines that only contain white space and comment characters
