DART enhancements to st_archive (#260)

* Added code to make st-archive handle DART files

* Updated config_archive.xml to focus only on DART needs.

Replaced previous mom_st-arch_dart version with a one focused on DART.
Additional (non-DART) proposed fixes will be in the next commit.

* Added fixes to non-DART-related regular expressions.
