Added a script to import resources from a csv file (as used by U of HI).
Changed the disciplines list, eg, to MPS.Astronomy and Multi-Science Facility.
Removed unneeded resourcedb upgrade scripts; resourcedb.sql matches current state.
Export script now skips writing out resources with discipline = "Unknown" or "nonscience". It also writes a csv file also, in case it's useful.
Added a script to fix disciplines in past elasticsearch data.
Moved scripts that are run by hand in various situations to a misc-scripts folder (that is not installed anywhere).
Misc minor changes.
