bugfix: inputs/SALVIAS/import_order.txt: added party_code_party_
moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
Added inputs/SALVIAS*/Source/, containing referenceType metadata
inputs/SALVIAS/plotMetadata/: LEFT JOINed with lookup_MethodCode to create plotMetadata_
inputs/SALVIAS/: Added projects/
inputs/SALVIAS/: Switched to using the DB export's staging tables instead of the exported CSVs
inputs/: Renamed subfolders to VegCSV names, using the steps at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV_subfolders#Rename-subfolders-to-VegCSV-names>
Inputs with multiple tables: Added explicit import_order.txt files, so that sort orders can later be removed from the subdir names
